StringBuilder Constructor (String, Int32, Int32, Int32)

Initializes a new instance of the StringBuilder class from the specified substring and capacity.

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

public StringBuilder(
	string value,
	int startIndex,
	int length,
	int capacity
)

Parameters

value
Type: System.String

The string that contains the substring used to initialize the value of this instance. If value is null, the new StringBuilder will contain the empty string (that is, it contains Empty).

startIndex
Type: System.Int32

The position within value where the substring begins.

length
Type: System.Int32

The number of characters in the substring.

capacity
Type: System.Int32

The suggested starting size of the StringBuilder.

ExceptionCondition
ArgumentOutOfRangeException

capacity is less than zero.

-or-

startIndex plus length is not a position within value.

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

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

string initialString = "Initial string for stringbuilder.";
int startIndex = 0;
int substringLength = 14;
int capacity = 255;
StringBuilder stringBuilder = new StringBuilder(initialString, 
    startIndex, substringLength, capacity);
