Types comparison in VB.NET

How i can compare type data type in VB.NET? My code:

Private Function Equal(ByVal parameter As String, ByVal paramenterName As String, ByVal dataType As Type) As String

    If dataType = String Then
        return 1;
    End If

 End Functio开发者_如何学编程n

Any ideas?

If dataType = GetType(String) Then
    return 1
End If

If datatype Is GetType(String) Then
    'do something
End If

Substitute Is for = and everything works

The accepted answer has a syntax error. Here is the correct solution:

If dataType = GetType(String) Then
    Return 1
End If

Or

 If dataType.Equals(GetType(String)) Then
      Return 1
 End If

Or

 If dataType Is GetType(String) Then
     Return 1
 End If

The last way is probably the best way to check because it won't throw an exception if the object is null.

Also see https://msdn.microsoft.com/en-us/library/system.object.gettype(v=vs.110).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-1

This is probably the best way to do it in VB.

If dataType Is String Then
    return 1
End If
