Converts the specified string representation of a number to an equivalent 32-bit signed integer.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Function ToInt32 ( _
value As String _
) As Integer
public static int ToInt32(
string value
)
public:
static int ToInt32(
String^ value
)
static member ToInt32 :
value:string -> int
public static function ToInt32(
value : String
) : int
Parameters
- value
Type: System. . :: . .String
A string that contains the number to convert.
Return Value
Type: System. . :: . .Int32
A 32-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is nullNothingnullptrunita null reference (Nothing in Visual Basic).
Exceptions
| Exception | Condition |
|---|---|
| FormatException | value does not consist of an optional sign followed by a sequence of digits (0 through 9). |
| OverflowException | value represents a number that is less than Int32..::..MinValue or greater than Int32..::..MaxValue. |
Remarks
Using the ToInt32(String) method is equivalent to passing value to the Int32..::..Parse(String) method. value is interpreted by using the formatting conventions of the current thread culture.
If you prefer not to handle an exception if the conversion fails, you can call the Int32.TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.
