Append Method (UInt64)

StringBuilder.Append Method (UInt64)

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

Appends the string representation of a specified 64-bit unsigned integer to the end of this instance.

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public StringBuilder Append(
	ulong value
)

Parameters

value
Type: System.UInt64
The 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.


System.Text.StringBuilder sb = new 
            System.Text.StringBuilder("The range of a 64-bit unsigned integer: ");
sb.Append(UInt64.MinValue).Append(" to ").Append(UInt64.MaxValue);
outputBlock.Text += sb + Environment.NewLine;
// The example displays the following output:
//       The range of a 64-bit unsigned integer: 0 to 18446744073709551615


The Append method calls the UInt64.ToString(IFormatProvider) 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.
