BitConverter.ToInt32 Method (Byte[], Int32)

 

Returns a 32-bit signed integer converted from four bytes at a specified position in a byte array.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

static member ToInt32 : 
        value:byte[] *
        startIndex:int -> int

Parameters

value
Type: System.Byte[]

An array of bytes.

startIndex
Type: System.Int32

The starting position within value.

Return Value

Type: System.Int32

A 32-bit signed integer formed by four bytes beginning at startIndex.

Exception Condition
ArgumentException

startIndex is greater than or equal to the length of value minus 3, and is less than or equal to the length of value minus 1.

ArgumentNullException

value is null.

ArgumentOutOfRangeException

startIndex is less than zero or greater than the length of value minus 1.

The ToInt32 method converts the bytes from index startIndex to startIndex + 3 to an Int32 value. The order of bytes in the array must reflect the endianness of the computer system's architecture; for more information, see the Remarks section of BitConverter.

The following example uses the ToInt32 method to create Int32 values from a four-byte array and from the upper four bytes of an eight-byte array. It also uses the GetBytes(Int32) and ToInt32 methods to round-trip an Int32 value.
