[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Appends a specified number of copies of the string representation of a Unicode character to the end of this instance.

Namespace:  System.Text
Assembly:  mscorlib (in mscorlib.dll)

Public Function Append ( _
	value As Char, _
	repeatCount As Integer _
) As StringBuilder


Type: System.Char
The character to append.
Type: System.Int32
The number of times to append value.

Return Value

Type: System.Text.StringBuilder
A reference to this instance after the append operation has completed.


repeatCount is less than zero.


Enlarging the value of this instance would exceed its maximum capacity.


Out of memory.

The Append method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.

Dim value As Decimal = 1346.19d
Dim sb As New System.Text.StringBuilder()
sb.Append("*"c, 5).AppendFormat("{0:C2}", value).Append("*"c, 5)
outputBlock.Text += sb.ToString() + Environment.NewLine
' The example displays the following output:
'       *****$1,346.19*****

The capacity of this instance is adjusted as needed.
