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.
ExceptionCondition
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.
