Int64Converter Class

Definition

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

Examples

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, String::typeid ) );
Console::WriteLine( TypeDescriptor::GetConverter( myInt64 )->ConvertFrom( myInt64String ) );
long myInt64 = -123456789123;
string myInt64String = "+184467440737095551";
Console.WriteLine(TypeDescriptor.GetConverter(myInt64).ConvertTo(myInt64, typeof(string))); 
Console.WriteLine(TypeDescriptor.GetConverter(myInt64).ConvertFrom(myInt64String));    
Dim myInt64 As Long = -123456789123
Dim myInt64String As String = "+184467440737095551"
Console.WriteLine(TypeDescriptor.GetConverter(myInt64).ConvertTo(myInt64, GetType(String)))
Console.WriteLine(TypeDescriptor.GetConverter(myInt64).ConvertFrom(myInt64String))

Remarks

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.

Note

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.
