Mid function and Mid Statement

Question

Hi What is difference between Mid function and Mid Statement ?

Vulpes · Answer

Both are members of the VB.NET runtime library Strings module. The indices used are 1-based rather than zero based. The Mid function returns a specified number of characters from 'the middle' of a string. For example: Dim s As String = Mid("Arun", 2, 2) returns the string "ru". Dim t As String = Mid("Arun", 2) returns "run". In contrast, the Mid statement replaces characters in 'the middle' of a string with another string. For example: Dim s As String = "The dog jumps" Mid(s, 5, 3) = "fox" returns "The fox jumps".

Hi Arun, Mid function returns the characters while the Mid statement replaces the characters. Example , Sub Main() Dim testString = "TestingStringHere" Mid(testString, 5) = "..Bore.." ' it is Mid statement Console.WriteLine(testString) ' returns Test..Bore..gHere - its replacing string Dim midstring As String = "TestingStringHere" midstring = Mid(midstring, 8, 6) ' it is Mid function Console.WriteLine(midstring) ' returns string - its just extracting string End Sub Thanks & Regards ----------------- Chintan Rathod
