How to: create strings using a StringBuilder in Visual Basic

  • Άρθρο

This example constructs a long string from many smaller strings using the StringBuilder class. The StringBuilder class is more efficient than the &= operator for concatenating many strings.

Example

The following example creates an instance of the StringBuilder class, appends 1,000 strings to that instance, and then returns its string representation:

Private Function StringBuilderTest() As String
    Dim builder As New System.Text.StringBuilder
    For i As Integer = 1 To 1000
        builder.Append("Step " & i & vbCrLf)
    Next
    Return builder.ToString
End Function
