StringBuilder::Insert Method (Int32, Boolean)
Inserts the string representation of a Boolean value into this instance at the specified character position.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- index
-
Type:
System::Int32
The position in this instance where insertion begins.
- value
-
Type:
System::Boolean
The value to insert.
Return Value
Type: System.Text::StringBuilder^A reference to this instance after the insert operation has completed.
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | index is less than zero or greater than the length of this instance. |
| OutOfMemoryException | Enlarging the value of this instance would exceed MaxCapacity. |
Boolean::ToString is used to get a string representation of value. Existing characters are shifted to make room for the new text. The capacity is adjusted as needed.
Notes to Callers:
In the .NET Framework 3.5 Service Pack 1 and earlier versions, calls to this method threw an ArgumentOutOfRangeException if inserting value would cause the object's total length to exceed MaxCapacity. Starting with the .NET Framework 4, the method throws an OutOfMemoryException.
The following example demonstrates the Insert method.
