UInt64Converter Class

Provides a type converter to convert 64-bit unsigned integer objects to and from other representations.

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

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class UInt64Converter : BaseNumberConverter


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This converter can only convert a 64-bit unsigned integer object to and from a string.

The UInt64 value type represents unsigned integers with values ranging from 0 to 184,467,440,737,095,551,615. This data type is not supported in Visual Basic.


You should never create an instance of a UInt64Converter. Instead, call the GetConverter method of TypeDescriptor. For more information, see the examples in the TypeConverter base class and How to: Implement a Type Converter.

The following code example converts a variable of type UInt64 to a string, and vice versa.

ulong myUInt64 = 123456789123;
string myUInt64String = "184467440737095551";
Console.WriteLine(TypeDescriptor.GetConverter(myUInt64).ConvertTo(myUInt64, typeof(string))); 

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
