An unhandled exception occurred during the execution of the current web request. ASP.NET

Question

I just ran my program and I got this error message

An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

with stack trace

[NullReferenceException: Object reference not set to an instance of an object.]
   OverseasCreditCard.Default.Page_Load(Object sender, EventArgs e) +667
   System.Web.UI.Control.LoadRecursive() +70
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3177

I am using ASP.NET C#, does anyone know what happened?

One of the variables/objects you are trying to access in `Page_load` is `null`. Put a break point in the method and debug it to find it. — chead23, Nov 12 '14 at 08:51

Incomplete information: we need to know which line is throwing the NullReferenceException in order to tell precisely where the problem lies.

Obviously, you are using an uninitialized variable (i.e., a variable that has been declared but not initialized) and try to access one of its non-static method/property/whatever.

Solution: - Find the line that is throwing the exception from the exception details - In this line, check that every variable you are using has been correctly initialized (i.e., it is not null)

Good luck.

This is not an answer. This is a request for information with at best some guidelines to troubleshoot the error. — Camilo Terevinto, Jun 07 '17 at 13:39

I had the same problem and found out that I had forgotten to include the script in the file which I want to include in the live site.

Also, you should try this:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));

Here is the code with line 156, it has try and catch above it

    /// <summary>
    /// Execute a SQL Query statement, using the default SQL connection for the application
    /// </summary>
    /// <param name="query">SQL query to execute</param>
    /// <returns>DataTable of results</returns>
    public static DataTable Query(string query)
    {
        DataTable results = new DataTable();
        string configConnectionString = "ApplicationServices";

        System.Configuration.Configuration WebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~/Web.config");
        System.Configuration.ConnectionStringSettings connString;

        if (WebConfig.ConnectionStrings.ConnectionStrings.Count > 0)
        {
            connString = WebConfig.ConnectionStrings.ConnectionStrings[configConnectionString];

            if (connString != null)
            {
                try
                {
                    using (SqlConnection conn = new SqlConnection(connString.ToString()))
                    using (SqlCommand cmd = new SqlCommand(query, conn))
                    using (SqlDataAdapter dataAdapter = new SqlDataAdapter(cmd))
                        dataAdapter.Fill(results);

                    return results;
                }
                catch (Exception ex)
                {
                    throw new SqlException(string.Format("SqlException occurred during query execution: ", ex));
                }
            }
            else
            {
                throw new SqlException(string.Format("Connection string for " + configConnectionString + "is null."));
            }
        }
        else
        {
            throw new SqlException(string.Format("No connection strings found in Web.config file."));
        }
    }
