After calling Webservices, it returns an object (This object is a custom object class) to client. So, I want to convert from this object to custom class.
-Webservices:
[WebMethod]
public Cls_ROLES GetRoles(int firstNum)
{
Cls_ROLES o = new Cls_ROLES();
o.Role_ID = 2;
o.RoleName = "binh";
return o;
}
-Client:
+Function:
public object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
{
System.Net.WebClient client = new System.Net.WebClient();
//-Connect To the web service
using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl"))
{
//--Now read the WSDL file describing a service.
ServiceDescription description = ServiceDescription.Read(stream);
///// LOAD THE DOM /////////
//--Initialize a service description importer.
ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
importer.AddServiceDescription(description, null, null);
//--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client;
//--Generate properties to represent primitive values.
importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;
//--Initialize a Code-DOM tree into which we will import the service.
CodeNamespace nmspace = new CodeNamespace();
CodeCompileUnit unit1 = new CodeCompileUnit();
unit1.Namespaces.Add(nmspace);
//--Import the service into the Code-DOM tree. This creates proxy code
//--that uses the service.
ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);
if (warning == 0) //--If zero then we are good to go
{
//--Generate the proxy code
CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp");
//--Compile the assembly proxy with the appropriate references
string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" };
CompilerParameters parms = new CompilerParameters(assemblyReferences);
CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1);
//-Check For Errors
if (results.Errors.Count > 0)
{
StringBuilder sb = new StringBuilder();
foreach (CompilerError oops in results.Errors)
{
sb.AppendLine("========Compiler error============");
sb.AppendLine(oops.ErrorText);
}
throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString());
}
//--Finally, Invoke the web service method
Type foundType = null;
Type[] types = results.CompiledAssembly.GetTypes();
foreach (Type type in types)
{
if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol))
{
Console.WriteLine(type.ToString());
foundType = type;
}
}
object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString());
MethodInfo mi = wsvcClass.GetType().GetMethod(methodName);
object o = new object();
o=mi.Invoke(wsvcClass, args);
return o;
}
else
{
return null;
}
}
}
+Page_Load function:
Line 1:object[] args=new object[1];
Line 2:args[0]=1;
Line 3:o = this.CallWebService("http://localhost:1814/HelloServices/Service.asmx", "Hello", "GetRoles", args);
it returns an object at Line3 (This object is a custom object class) to client. So, I want to convert from this object to custom class(Cls_Role object). //====================================================================================== //====================================================================================== //====================================================================================== As Selalu_Ingin_Belajar's answer,I can get value from webservices to client fine.
object yourObject = new object();
foreach (PropertyInfo property in yourObject.GetType().GetProperties())
{
object value = property.GetValue(yourObject , null);
Console.WriteLine("{0} = {1}", property.Name, value);
}
Beside it,When I apply to another project,It show another error: Parameter count mismatch. If I use AddWebReference by VisualStudio tool. It'll auto generate Reference.cs file.It contain:
/// <remarks/>
[System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace="urn:ALBAPI", ResponseNamespace="urn:ALBAPI")]
[return: System.Xml.Serialization.SoapElementAttribute("info")]
public ResponseInfo getSetupLicenseRows(out SetupLicenseRowsValues values) {
object[] results = this.Invoke("getSetupLicenseRows", new object[0]);
values = ((SetupLicenseRowsValues)(results[1]));
return ((ResponseInfo)(results[0]));
}
So that,It's easy to call from webClient by passing a object SetupLicenseRowsValues class. Now,I must pass parameter to WebServices by manually.Don't use this generate file.
Client:
public object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
{
System.Net.WebClient client = new System.Net.WebClient();
//-Connect To the web service
using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl"))
{
//--Now read the WSDL file describing a service.
ServiceDescription description = ServiceDescription.Read(stream);
///// LOAD THE DOM /////////
//--Initialize a service description importer.
ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
importer.AddServiceDescription(description, null, null);
//--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client;
//--Generate properties to represent primitive values.
importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;
//--Initialize a Code-DOM tree into which we will import the service.
CodeNamespace nmspace = new CodeNamespace();
CodeCompileUnit unit1 = new CodeCompileUnit();
unit1.Namespaces.Add(nmspace);
//--Import the service into the Code-DOM tree. This creates proxy code
//--that uses the service.
ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);
if (warning == 0) //--If zero then we are good to go
{
//--Generate the proxy code
CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp");
//--Compile the assembly proxy with the appropriate references
string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" };
CompilerParameters parms = new CompilerParameters(assemblyReferences);
CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1);
//-Check For Errors
if (results.Errors.Count > 0)
{
StringBuilder sb = new StringBuilder();
foreach (CompilerError oops in results.Errors)
{
sb.AppendLine("========Compiler error============");
sb.AppendLine(oops.ErrorText);
}
throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString());
}
//--Finally, Invoke the web service method
Type foundType = null;
Type[] types = results.CompiledAssembly.GetTypes();
foreach (Type type in types)
{
if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol))
{
Console.WriteLine(type.ToString());
foundType = type;
}
}
object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString());
MethodInfo mi = wsvcClass.GetType().GetMethod(methodName);
object o = new object();
Line error: o = mi.Invoke(wsvcClass, new object[0]);
return o;
}
else
{
return null;
}
}
}
public void call()
{
string WebserviceUrl = "http://192.168.2.19:3333/ALBAPI.wsdl";
string serviceName = "ALBAPI";
string methodName = "getSetupLicenseRows";
object[] args=new object[0];
object sSessionID = CallWebService(WebserviceUrl, serviceName, methodName,args);
foreach (PropertyInfo property in sSessionID.GetType().GetProperties())
{
object value = property.GetValue(sSessionID, null);
Console.WriteLine("{0} = {1}", property.Name, value);
}
}
Now,It show error "Parameter count mismatch" at Line error. Thanks for your help anyway
