Sample Code

You can now use members of the Visual Basic .NET run-time library in Visual C#. The following code demonstrates how to use the IsNumeric function, which is a member of the Microsoft.VisualBasic.Information class:

private void UseIsNumeric()
{
     string s = "123";
     bool bResult1, bResult2;
     bResult1 = Information.IsNumeric(s);
     // bResult1 now equals true
     s = "Hello";
     bResult2 = Information.IsNumeric(s);
     // bResult2 now equals false
}
