Syntax
Public Function Append ( _
value As String _
) As StringBuilder
public StringBuilder Append(
string value
)

Exceptions
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | Enlarging the value of this instance would exceed its maximum capacity. |
Remarks
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 flag As Boolean = false
Dim sb As New System.Text.StringBuilder
sb.Append("The value of the flag is ").Append(flag).Append(".")
outputBlock.Text += sb.ToString() + Environment.NewLine
' The example displays the following output:
' The value of the flag is False.
bool flag = false;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("The value of the flag is ").Append(flag).Append(".");
outputBlock.Text += sb.ToString() + Environment.NewLine;
// The example displays the following output:
// The value of the flag is False.
If value is nullNothingnullptra null reference (Nothing in Visual Basic), no changes are made.
The capacity of this instance is adjusted as needed.
