In visual basic, the string Join method is useful to concatenate all the elements of string array using the specified separator between each element.
Following is the pictorial representation of joining two string elements in an array with the specified separator using the Join() method in a visual basic programming language.
If you observe the above diagram, we are concatenating two array elements ”Suresh” and “Dasari” by using Join method with defined separator “, ” and the Join method has returned the string like “Suresh, Dasari”.
Following is the syntax of defining a Join method to append or concatenate string array elements using a specified separator in a visual basic programming language.
Public Shared Function Join(ByVal separator As String, ByVal ParamArray values As String()) As String
Public Shared Function Join(ByVal separator As String, ByVal ParamArray values As Object()) As String
Public Shared Function Join(ByVal separator As String, ByVal values As IEnumerable(Of String)) As String
If you observe the above syntaxes, the Join method will append or concatenate all the items of array or list using the specified separator between each element.
Following is the example of using Join() method to append or concatenate all the string array elements using a specified separator in a visual basic programming language.
Module Module1
Sub Main()
Dim sArr As String() = {"Welcome", "to", "Tutlane"}
Console.WriteLine("Join with Hypen: {0}", String.Join("-", sArr))
Dim sArr1 As String() = {"Suresh", "Rohini", "Trishika"}
Console.WriteLine("Join with Comma: {0}", String.Join(", ", sArr1))
Console.WriteLine("Press Enter Key to Exit..")
Console.ReadLine()
End Sub
End Module
If you observe the above example, we used a string Join() method to append or concatenate all the elements of string array using a specified separator.
When we execute the above visual basic program, we will get the result as shown below.
This is how we can use the string Join() method to append or concatenate all string array elements using a specified separator in a visual basic programming language.
