StringBuilder Constructor (String, Int32)

.NET Framework 4

Other Versions

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

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

Syntax

C++

Copy

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.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	capacity is less than zero.

Remarks

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.

Examples

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

C++

Copy


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