StringBuilder Constructor (Int32, Int32)

July 28, 2014

Initializes a new instance of the StringBuilder class that starts with a specified capacity and can grow to a specified maximum.

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

public StringBuilder(
	int capacity,
	int maxCapacity
)

Parameters

capacity
Type: System.Int32
The suggested starting size of the StringBuilder.
maxCapacity
Type: System.Int32
The maximum number of characters the current string can contain.

ExceptionCondition
ArgumentOutOfRangeException

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 that is 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 0 (zero), the implementation-specific default capacity is used.

The maxCapacity parameter defines the maximum number of characters that the current instance can hold. 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.

The following code example demonstrates how to call the StringBuilder constructor with a specified capacity and maximum capacity.


int capacity = 255;
int maxCapacity = 1024;
StringBuilder stringBuilder =
    new StringBuilder(capacity, maxCapacity);
