StringBuilder Constructor (Int32, Int32)
Initializes a new instance of the StringBuilder class that starts with a specified capacity and can grow to a specified maximum.
Assembly: mscorlib (in mscorlib.dll)
maxCapacity is less than one, capacity is less than zero, or capacity is greater than maxCapacity.
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 maxCapacity property defines the maximum number of characters that the current instance can hold. Its value is assigned to the MaxCapacity property. If the number of characters to be stored in the current instance exceeds this maxCapacity value, the StringBuilder object does not allocate additional memory, but instead throws an exception.Notes to Callers
In the .NET Framework 4, when you instantiate the StringBuilder object by calling the constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the Append and AppendFormat methods to append small strings.
