StringBuilder Constructor (String, Int32, Int32, Int32)

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

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

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

Syntax

'Declaration
Public Sub New ( _
    value As String, _
    startIndex As Integer, _
    length As Integer, _
    capacity As Integer _
)

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

public:
StringBuilder(
    String^ value, 
    int startIndex, 
    int length, 
    int capacity
)

new : 
        value:string * 
        startIndex:int * 
        length:int * 
        capacity:int -> StringBuilder

public function StringBuilder(
    value : String, 
    startIndex : int, 
    length : int, 
    capacity : int
)

Parameters

  • value
    Type: System. . :: . .String
    The string that contains the substring used to initialize the value of this instance. If value is nullNothingnullptrunita null reference (Nothing in Visual Basic), the new StringBuilder will contain the empty string (that is, it contains Empty).

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.
