How to call Visual Basic .NET run-time library members from Visual C#


This step-by-step article describes how to use the members that are provided by the Microsoft Visual Basic .NET run-time library in a Visual C# application.

Add a Reference to the Visual Basic .NET Run-Time Library

  1. In a Visual C# application, click the Project menu, and then click Add Reference.
  2. In the Component Name list, click Microsoft Visual Basic .NET Runtime to add Microsoft.VisualBasic.dll.
  3. At the top of the source file, add the following statement:
    using Microsoft.VisualBasic;

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
