StringBuilder.Append Method (Boolean)

July 28, 2014

Appends the string representation of a specified Boolean value to the end of this instance.

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

public StringBuilder Append(
	bool value
)

Parameters

value
Type: System.Boolean
The Boolean value to append.

Return Value

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

ExceptionCondition
ArgumentOutOfRangeException

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.


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.


The Append method calls the Boolean.ToString() method to get the string representation of value. The capacity of this instance is adjusted as needed.
