StringBuilder.Append Method (Char)

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

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

Public Function Append ( _
	value As Char _
) As StringBuilder


Type: System.Char
The Unicode character to append.

Return Value

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


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

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 str As String = "Characters in a string."
Dim sb As New System.Text.StringBuilder()
For Each ch In str
   sb.Append(" '").Append(ch).Append("' ")
outputBlock.Text += "Characters in the string:" + vbCrLf
outputBlock.Text += String.Format("  {0}", sb) + vbCrLf
' The example displays the following output:
'    Characters in the string:
'       'C'  'h'  'a'  'r'  'a'  'c'  't'  'e'  'r'  's'  ' '  'i'  'n'  ' '  'a'  ' '  's'  't' 'r'  'i'  'n'  'g'  '.'      

The capacity of this instance is adjusted as needed.
