StringBuilder Constructor (Int32)

 

Initializes a new instance of the StringBuilder class using the specified capacity.

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

public StringBuilder(
	int capacity
)

Parameters

capacity
Type: System.Int32

The suggested starting size of this instance.

Exception Condition
ArgumentOutOfRangeException

capacity is less than zero.

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.

The string value of this instance is set to String.Empty. If capacity is zero, the implementation-specific default capacity is used.

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

int capacity = 255;
StringBuilder stringBuilder = new StringBuilder(capacity);
