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

Syntax

'Declaration
Public Function Append ( _
    value As Long _
) As StringBuilder
public StringBuilder Append(
    long value
)

Parameters

Return Value

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

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 sb As New System.Text.StringBuilder("The range of a 64-bit integer: ")
sb.Append(Int64.MinValue).Append(" to ").Append(Int64.MaxValue)
outputBlock.Text += sb.ToString() + vbCrLf
' The example displays the following output:
'       The range of a 64-bit integer:  -9223372036854775808 to 9223372036854775807
System.Text.StringBuilder sb = new 
            System.Text.StringBuilder("The range of a 64-bit integer: ");
sb.Append(Int64.MinValue).Append(" to ").Append(Int64.MaxValue);
outputBlock.Text += sb.ToString() + Environment.NewLine;
// The example displays the following output:
//       The range of a 64-bit integer:  -9223372036854775808 to 9223372036854775807

The Append method calls the Int64.ToString(IFormatProvider) 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.
