Initializes a new instance of the StringBuilder class using the specified capacity.
public:
StringBuilder(int capacity);
public StringBuilder (int capacity);
new System.Text.StringBuilder : int -> System.Text.StringBuilder
Public Sub New (capacity As Integer)
Parameters
- capacity
- Int32
The suggested starting size of this instance.
Exceptions
capacity
is less than zero.
Examples
The following example demonstrates how to call the StringBuilder constructor with a specified capacity.
int capacity = 255;
StringBuilder^ stringBuilder = gcnew StringBuilder( capacity );
int capacity = 255;
StringBuilder stringBuilder = new StringBuilder(capacity);
let capacity = 255
let stringBuilder = StringBuilder capacity
Dim capacity As Integer = 255
Dim stringBuilder As New StringBuilder(capacity)
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.
The string value of this instance is set to String.Empty. If capacity
is zero, the implementation-specific default capacity is used.

Initializes a new instance of the StringBuilder class that starts with a specified capacity and can grow to a specified maximum.
public:
StringBuilder(int capacity, int maxCapacity);
public StringBuilder (int capacity, int maxCapacity);
new System.Text.StringBuilder : int * int -> System.Text.StringBuilder
Public Sub New (capacity As Integer, maxCapacity As Integer)
Parameters
- capacity
- Int32
The suggested starting size of the StringBuilder.
- maxCapacity
- Int32
The maximum number of characters the current string can contain.
Exceptions
maxCapacity
is less than one, capacity
is less than zero, or capacity
is greater than maxCapacity
.
Examples
The following example demonstrates how to call the StringBuilder constructor with a specified capacity and maximum capacity.
int capacity = 255;
int maxCapacity = 1024;
StringBuilder^ stringBuilder = gcnew StringBuilder( capacity,maxCapacity );
int capacity = 255;
int maxCapacity = 1024;
StringBuilder stringBuilder =
new StringBuilder(capacity, maxCapacity);
let capacity = 255
let maxCapacity = 1024
let stringBuilder = StringBuilder(capacity, maxCapacity)
Dim capacity As Integer = 255
Dim maxCapacity As Integer = 1024
Dim stringBuilder As New StringBuilder(capacity, maxCapacity)
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.
The maxCapacity
property defines the maximum number of characters that the current instance can hold. Its value is assigned to the MaxCapacity property. If the number of characters to be stored in the current instance exceeds this maxCapacity
value, the StringBuilder object does not allocate additional memory, but instead throws an exception.
Notes to Callers
In .NET Core and in the .NET Framework 4.0 and later versions, when you instantiate the StringBuilder object by calling the StringBuilder(Int32, Int32) constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the Append(String) and AppendFormat(String, Object) methods to append small strings.

public StringBuilder (string value, int capacity);
public StringBuilder (string? value, int capacity);
new System.Text.StringBuilder : string * int -> System.Text.StringBuilder
Public Sub New (value As String, capacity As Integer)
Parameters
- value
- 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
- Int32
The suggested starting size of the StringBuilder.
Exceptions
capacity

String^ initialString = L"Initial string. ";
int capacity = 255;
StringBuilder^ stringBuilder = gcnew StringBuilder(

Initializes a new instance of the StringBuilder class from the specified substring and capacity.
public:
StringBuilder(System::String ^ value, int startIndex, int length, int capacity);
public StringBuilder (string value, int startIndex, int length, int capacity);
public StringBuilder (string? value, int startIndex, int length, int capacity);
new System.Text.StringBuilder : string * int * int * int -> System.Text.StringBuilder
Public Sub New (value As String, startIndex As Integer, length As Integer, capacity As Integer)
Parameters
- value
- 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).

- Int32
The position within value
where the substring begins.
- length
- Int32
The number of characters in the substring.
- capacity
- Int32
The suggested starting size of the StringBuilder.
Exceptions
capacity
is less than zero.
-or-
startIndex
plus length
is not a position within value
.
Examples
The following example demonstrates how to call the StringBuilder constructor with the specified string.
String^ initialString = L"Initial string for stringbuilder.";
int startIndex = 0;
int substringLength = 14;
int capacity = 255;
StringBuilder^ stringBuilder = gcnew StringBuilder(
initialString,startIndex,substringLength,capacity );
string initialString = "Initial string for stringbuilder.";
int startIndex = 0;
int substringLength = 14;
int capacity = 255;
StringBuilder stringBuilder = new StringBuilder(initialString,
startIndex, substringLength, capacity);
let initialString = "Initial string for stringbuilder."
let startIndex = 0
let substringLength = 14
let capacity = 255
let stringBuilder =
StringBuilder(initialString, startIndex, substringLength, capacity)
Dim initialString As String = "Initial string for stringbuilder."
Dim startIndex As Integer = 0
Dim substringLength As Integer = 14
Dim capacity As Integer = 255
Dim stringBuilder As New StringBuilder(initialString, _
startIndex, substringLength, capacity)
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
