I want to call a wcf service function from my c# client, that service was at remote site. so need to call that function by dynamic linking the service.
On calling the function and passing the required parameters, it is throwing an exception that
"Object of type 'TMsgInParam' cannot be converted to type 'omni.infrasofttech.com.TMsgInParam'"
So I need to know how to pass the complex type parameters to that function.
Now here is the wsdl file data of that service to which i have to connect:

Now I am calling this service Invoke function by the following code
Uri mexAddress = new Uri("http://192.168.100.108:8080/PassOmni30/OmniService.asmx?wsdl");
// For MEX endpoints use a MEX address and a
// mexMode of .MetadataExchange

string operationName = "Invoke";
object[] operationParameters = new object[4];

MsgInParam.Field1 = "Name";
MsgInParam.Field2 = "Age";
MsgInParam.Field3 = "Address";
MsgInParam.Field4 = "DOB";
MsgInParam.Field5 = "Contact";
//add parameters
operationParameters[0] = "1";
operationParameters[1] = "1";
operationParameters[2] = 82;
operationParameters[3] = MsgInParam;
// Get the metadata file from the service.
MetadataExchangeClient mexClient = new MetadataExchangeClient(mexAddress, mexMode);
mexClient.ResolveMetadataReferences = true;
MetadataSet metaSet = mexClient.GetMetadata();
// Import all contracts and endpoints
WsdlImporter importer = new WsdlImporter(metaSet);
Collection<ContractDescription> contracts = importer.ImportAllContracts();
ServiceEndpointCollection allEndpoints = importer.ImportAllEndpoints();

ServiceContractGenerator generator = new ServiceContractGenerator();
var endpointsForContracts = new Dictionary<string, IEnumerable<ServiceEndpoint>>();
foreach (ContractDescription contract in contracts)
{
generator.GenerateServiceContractType(contract);
// Keep a list of each contract's endpoints
endpointsForContracts[contract.Name] = allEndpoints.Where(
se => se.Contract.Name == contract.Name).ToList();
}
if (generator.Errors.Count != 0)
throw new Exception("There were errors during code compilation.");
// Generate a code file for the contracts
CodeGeneratorOptions options = new CodeGeneratorOptions();
options.BracingStyle = "C";
CodeDomProvider codeDomProvider = CodeDomProvider.CreateProvider("C#");
// Compile the code file to an in-memory assembly
// Don't forget to add all WCF-related assemblies as references
CompilerParameters compilerParameters = new CompilerParameters(
new string[] {
"System.dll", "System.ServiceModel.dll",
"System.Runtime.Serialization.dll" });
compilerParameters.GenerateInMemory = true;
CompilerResults results = codeDomProvider.CompileAssemblyFromDom(compilerParameters, generator.TargetCompileUnit);
if (results.Errors.Count > 0)
{
throw new Exception("There were errors during generated code compilation");
}
else
{
// Find the proxy type that was generated for the specified contract

// to the ctor
object instance = results.CompiledAssembly.CreateInstance(
clientProxyType.Name,
false,
System.Reflection.BindingFlags.CreateInstance,
null,
new object[] { se.Binding, se.Address },
CultureInfo.CurrentCulture, null);
// Get the operation's method, invoke it, and get the return value
object retVal = instance.GetType().GetMethod(operationName).Invoke(instance, operationParameters);
MessageBox.Show("Login reply received- " + retVal.ToString());
}
And defination of those complex datatype i have given is this in global scope
