Convert.ToInt32 Method (UInt32)

 

Converts the value of the specified 32-bit unsigned integer to an equivalent 32-bit signed integer.

This API is not CLS-compliant.

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

[CLSCompliantAttribute(false)]
public static int ToInt32(
	uint value
)

Parameters

value
Type: System.UInt32

The 32-bit unsigned integer to convert.

Return Value

Type: System.Int32

A 32-bit signed integer that is equivalent to value.

Exception Condition
OverflowException

value is greater than Int32.MaxValue.

The following example attempts to convert each element in an array of unsigned integers to a signed integer.

uint[] numbers = { UInt32.MinValue, 121, 340, UInt32.MaxValue };
int result;
foreach (uint number in numbers)
{
   try {
      result = Convert.ToInt32(number);
      Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                        number.GetType().Name, number,
                        result.GetType().Name, result);
   }
   catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the Int32 type.",
                        number.GetType().Name, number);
   }
}
// The example displays the following output:
//    Converted the UInt32 value 0 to the Int32 value 0.
//    Converted the UInt32 value 121 to the Int32 value 121.
//    Converted the UInt32 value 340 to the Int32 value 340.
//    The UInt32 value 4294967295 is outside the range of the Int32 type.
