StringBuilder Constructor (String, Int32, Int32, Int32)
Initializes a new instance of the StringBuilder class from the specified substring and capacity.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.String
The position within value where the substring begins.
The number of characters in the substring.
capacity is less than zero.
startIndex plus length is not a position within value.
The capacity parameter defines the maximum number of characters that can be stored in the memory allocated by the current instance. Its value is assigned to the Capacity property. If the number of characters to be stored in the current instance exceeds this capacity value, the StringBuilder object allocates additional memory to store them.
If capacity is zero, the implementation-specific default capacity is used.
The following example demonstrates how to call the StringBuilder constructor with the specified string.
