  • Interesting .Net String Functions

    Introduction: .Net 3.5 has some interesting string functions. I almost admire their usage. Following are those functions that we will be discussing here. String.IsNullOrEmpty() String.Split()(Available from .Net 1.0) String.Join()(Available from .Net 1.0) Reference Links String.IsNullOrEmpty - http://msdn.microsoft.com/en-us/library/system.string.isnullorempty.aspx String.Split() -http://msdn.microsoft.com/en-us/library/system.string.split.aspx String.Join()-http://msdn.microsoft.com/en-us/library/system.string.join.aspx Target Audience: The target audience should have knowledge in VB.Net or C#.Net to get a clear understanding of these functions.

This is something equal to VB.Net Dim tstStr As String If tstStr = String.Empty Or tstStr = Nothing Then Response.Write("String is empty or null") End
