Inserts a specified instance of
String at a specified index position in this instance.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Visual Basic (Declaration)
Public Function Insert ( _
startIndex As Integer, _
value As String _
) As String
Dim instance As String
Dim startIndex As Integer
Dim value As String
Dim returnValue As String
returnValue = instance.Insert(startIndex, value)
public string Insert (
int startIndex,
string value
)
public:
String^ Insert (
int startIndex,
String^ value
)
public String Insert (
int startIndex,
String value
)
public function Insert (
startIndex : int,
value : String
) : String
Parameters
- startIndex
The index position of the insertion.
- value
The String to insert.
Return Value
A new String equivalent to this instance but with value inserted at position startIndex.
If startIndex is equal to the length of this instance, value is appended to the end of this instance.
For example, the return value of "abc".Insert(2, "XYZ") is "abXYZc".
The following console application provides a simple demonstration of the Insert method.
