Question

I created a WCF service to communicate with database, first I created a sample Helloworld! method it’s working fine

but when I try to call the actual methods it’s giving following exception

An error occurred while receiving the HTTP response to http://10.11.32.211:87/Service.svc. This could be due to the service endpoint binding not using the HTTP protocol.

In the browser

An existing connection was forcibly closed by the remote host

My web.config file

<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>

<!--<system.serviceModel>
<behaviors>

    <behavior name="">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
</system.serviceModel>-->

I go through these links but it didn’t worked
MSDN LINK1

Edit

Actually what I am doing with this service is to execute a stored procedure on the server

using (con = new SqlConnection(connectionString))
        {
            using (cmd = new SqlCommand(selectStatement, con) { CommandType = CommandType.StoredProcedure })
            {
                adapter = new SqlDataAdapter(cmd);
                table = new DataTable();
                adapter.Fill(table);
                return table;
            }
        }

I am able to call the same stored procedure from different website manually but not using this service….

What is it? and why this is coming?

Answer 1

i found the answer for this here, we just need to instantiate the datatable with a specified name in its constructor

like

DataTable dt = new DataTable("TableName");

I don’t know why this gives error but this solved the issue……..
