Convert.ToInt32 Method (UInt64)
Converts the value of the specified 64-bit unsigned integer to an equivalent 32-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.UInt64
The 64-bit unsigned integer to convert.
| Exception | Condition |
|---|---|
| OverflowException | value is greater than Int32.MaxValue. |
The following example attempts to convert each element in an array of unsigned long integers to a signed integer.
ulong[] numbers = { UInt64.MinValue, 121, 340, UInt64.MaxValue }; int result; foreach (ulong number in numbers) { try { result = Convert.ToInt32(number); Console.WriteLine("Converted the {0} value {1} to a {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 UInt64 value 0 to a Int32 value 0. // Converted the UInt64 value 121 to a Int32 value 121. // Converted the UInt64 value 340 to a Int32 value 340. // The UInt64 value 18446744073709551615 is outside the range of the Int32 type.
