Problem in creating dll

[cmrhema]

Hello

I have created a small asp.net application wherein I just called a class

namespace dllconversion 
{

public partial class _Default : System.Web.UI.Page

{

 

protected void Page_Load(object sender, EventArgs e) 
{

 

 

}

public class c1

{

public string abc(string a1) 
{

 

return a1+"ok"; 
}

}



 

}
}

Here I just added the namespace and created a dll .

Imported this dll to another page successfully.

Now I just modified the dll a bit

I haved added a button and textbox

namespace dllconversion 
{

public partial class _Default : System.Web.UI.Page

{

 

protected void Page_Load(object sender, EventArgs e) 
{

 

 

} 
public class c1

{

public string abc(string a1) 
{

 

return a1+"ok"; 
}

}

protected void Button1_Click(object sender, EventArgs e) 
{

TextBox1.Text = "button event"; 
}

}

 

 

}

Now when I create the dll in the command prompt

E:\Converttodll>csc /t:library default.aspx.cs

I have the error as


Default.aspx.cs (35,13): error CS0103: The name 'TextBox1' does not exist in the current context

Please let me know what's the problem
