How to define using statements in web.config?

I'm using MySql in my asp.net project. But I don't want to type every "using MySql.Data.MySqlClient;" statement in every aspx.cs/aspx.vb file. How can I define this lines in web.config file?

I've defined some namespaces like below but this only works for aspx pages:

<?xml version="1.0"?>
<configuration>
    <system.web>
        <compilation debug="false" targetFramework="4.0"/>
        <pages>
            <namespaces>
                <add namespace="System.Web.Configurat开发者_开发知识库ion"/>
                <add namespace="MySql.Data"/>
                <add namespace="MySql.Data.MySqlClient"/>
            </namespaces>
        </pages>
    </system.web>
</configuration>

There is no way to setup global usings for the code-behinds. You have to put the usings in the code files.

Yes you can. If you open %Program Files%\Microsoft Visual Studio 8\Common7\IDE\ItemTemplates\CSharp\1033\Class.zip, Or: %Program Files%\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp\Code\1033

You can modify the class.cs file within that's used to generate all new C# source files - it looks like this:

using System;
using System.Collections.Generic;
using System.Text;

namespace $rootnamespace$
{
    class $safeitemrootname$
    {
    }
}

Also, there is a file called Class.vstemplate. Open this and you can edit the following:

<Reference>
    <Assembly>System</Assembly>
        </Reference>
        <Reference>
            <Assembly>System.Data</Assembly>
        </Reference>
        <Reference>
            <Assembly>System.Xml</Assembly>
        </Reference>
    </References>

Just wrap your using block in a #region and collapse it. No more worry about how many usings there are.
