Syntax

'Declaration
Public Shared Function ToInt32 ( _
    value As Object, _
    provider As IFormatProvider _
) As Integer

public static int ToInt32(
    Object value,
    IFormatProvider provider
)

Parameters

Return Value

Type: System.Int32
A 32-bit signed integer equivalent to the value of value, or zero if value is nulla null reference (Nothing in Visual Basic).

Exceptions

Exception Condition
InvalidCastException

value does not implement IConvertible.

Remarks

The return value is the result of invoking the IConvertible.ToInt32 method of the underlying type of value.

provider enables the user to specify culture-specific conversion information about the contents of value. For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number.

The base types ignore provider; however, it is honored if value is a user-defined type that implements the IConvertible interface.
