This API is not CLS-compliant.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-

System.UInt64
The 64-bit unsigned integer to convert.
| Exception | Condition |
|---|---|
| OverflowException | value is greater than UInt32.MaxValue. |
The following example attempts to convert each element in an unsigned long integer array to an unsigned integer value.
ulong[] numbers = { UInt64.MinValue, 121, 340, UInt64.MaxValue }; uint result; foreach (ulong number in numbers) { try { result = Convert.ToUInt32(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 UInt32 type.", number.GetType().Name, number); } } // The example displays the following output: // Converted the UInt64 value 0 to the UInt32 value 0. // Converted the UInt64 value 121 to the UInt32 value 121. // Converted the UInt64 value 340 to the UInt32 value 340. // The UInt64 value 18446744073709551615 is outside the range of the UInt32 type.
