StringBuilder.Clear Method
Visual Studio 2010
Removes all characters from the current StringBuilder instance.
Assembly: mscorlib (in mscorlib.dll)
Clear is a convenience method that is equivalent to setting the Length property of the current instance to 0 (zero).
Calling the Clear method does not modify the current instance's Capacity and MaxCapacity properties.
The following example instantiates a StringBuilder object with a string, calls the Clear method, and then appends a new string.
Imports System.Text Module Example Public Sub Main() Dim sb As New StringBuilder("This is a string.") Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length) sb.Clear() Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length) sb.Append("This is a second string.") Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length) End Sub End Module ' The example displays the following output: ' This is a string. (17 characters) ' (0 characters) ' This is a second string. (24 characters)
