StringBuilder Constructor (String, Int32)

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

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

public StringBuilder(
	string value,
	int capacity
)

Parameters

value
Type: System.String
The string used to initialize the value of the instance. If value is null, the new StringBuilder will contain the empty string (that is, it contains Empty).
capacity
Type: System.Int32
The suggested starting size of the StringBuilder.

ExceptionCondition
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.

If capacity is zero, the implementation-specific default capacity is used.

The following example demonstrates how to call the StringBuilder constructor with an initial string and a specified capacity.


string initialString = "Initial string. ";
int capacity = 255;
StringBuilder stringBuilder = 
    new StringBuilder(initialString, capacity);
