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

member Length : int with get, set

Property Value

Type: System.Int32
The length of this instance.

ExceptionCondition
ArgumentOutOfRangeException

The value specified for a set operation is less than zero or greater than MaxCapacity.

Like the String.Length property, the Length property indicates the length of the current string object. Unlike the String.Length property, which is read-only, the Length property allows you to modify the length of the string stored to the StringBuilder object.

If the specified length is less than the current length, the current StringBuilder object is truncated to the specified length. If the specified length is greater than the current length, the end of the string value of the current StringBuilder object is padded with the Unicode NULL character (U+0000).

If the specified length is greater than the current capacity, Capacity increases so that it is greater than or equal to the specified length.

The following example demonstrates the Length property.
