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)

[<HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)>]
type Int64Converter =  
    class
        inherit BaseNumberConverter
    end

The Int64Converter type exposes the following members.

  NameDescription

Public methodCreateInstance(ITypeDescriptorContext, IDictionary)Creates an instance of the type that this TypeConverter is associated with, using the specified context, given a set of property values for the object. (Inherited from TypeConverter.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)

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.

NoteNote

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.

NoteNote

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.

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

No code example is currently available or this language may not be supported.
