StringBuilder Constructor (String, Int32)
Initializes a new instance of the StringBuilder class using the specified string and capacity.
Assembly: mscorlib (in mscorlib.dll)
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.
