StringBuilder.Append Method (Byte)

Updated: January 2011

Appends the string representation of a specified 8-bit unsigned integer to the end of this instance.

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

public StringBuilder Append(
	byte value


Type: System.Byte
The value 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.

Byte[] bytes = { 16, 132, 27, 253 };
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (var value in bytes)
   sb.Append(value).Append(" ");         

outputBlock.Text += String.Format("The byte array: {0}\n", sb.ToString());
// The example displays the following output:
//         The byte array: 16 132 27 253      

The Append method calls the ToString method to get the string representation of value for the current culture. To control the formatting of value, call the AppendFormat method.

The capacity of this instance is adjusted as needed.
