Int64Converter Class

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

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

public class Int64Converter : BaseNumberConverter

Not applicable.

This converter can only convert a 64-bit signed integer object to and from a string. The Int64 value type represents integers with values ranging from negative 9,223,372,036,854,775,808 through positive 9,223,372,036,854,775,807.

The ConvertFrom method uses the Parse method of Int64 with the integer value of NumberStyles.

The ConvertTo method uses the general ("G") format for the string returned.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.


You should never create an instance of an Int64Converter. Instead, call the GetConverter method of TypeDescriptor. For more information, see the examples in the TypeConverter base class.

The HostProtectionAttribute attribute applied to this class 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.

The following sample converts a variable of type Int64 to a string, and vice versa.

long myInt64 = -123456789123;
string myInt64String = "+184467440737095551";
Console.WriteLine(TypeDescriptor.GetConverter(myInt64).ConvertTo(myInt64, typeof(string))); 

long myInt64 = -123456789123L;
String myInt64String = "+184467440737095551";
    ConvertTo((Int64)myInt64, String.class.ToType()));

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