StringBuilder.Insert Method (Int32, Decimal)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Inserts the string representation of a decimal number into this instance at the specified character position.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Function Insert ( _
index As Integer, _
value As Decimal _
) As StringBuilder
public StringBuilder Insert(
int index,
decimal value
)
Parameters
- index
Type: System..::.Int32
The position in this instance where insertion begins.
- value
Type: System..::.Decimal
The value to insert.
Return Value
Type: System.Text..::.StringBuilder
A reference to this instance after the insert operation has completed.
Exceptions
| 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. |
Remarks
Decimal..::.ToString is used to get a string representation of value. Existing characters are shifted to make room for the new text. The capacity of this instance 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 version 4, the method throws an OutOfMemoryException.
Examples
The following example demonstrates the Insert method.
