I have used VB.Net and now learning C#. I have the following line from
vb.net app:

id = CType(Request.QueryString("id"), System.Int32)

where id is type integer. I am trying the same under C# with:

id = (System.Int32)ctx.Request.QueryString["reportid"].ToString();

which gets compile error "(31): Cannot convert type 'string' to 'int'"

Any ideas?

Try using Convert.To... :

int id = Convert.ToInt32 (sMyString);
