UnitConverter 类

定义

Unit 对象转换为其他数据类型的对象,和从其他类型转换为 Unit 对象。Converts from a Unit object to an object of another data type and from another type to a Unit object.

public ref class UnitConverter : System::ComponentModel::TypeConverter
public class UnitConverter : System.ComponentModel.TypeConverter
type UnitConverter = class
    inherit TypeConverter
Public Class UnitConverter
Inherits TypeConverter
继承
UnitConverter

注解

UnitConverter使用类Unit将转换为另一种数据类型的对象。Use the UnitConverter class to convert a Unit to an object of another data type. 还可以使用UnitConverter类将另一种数据类型的对象转换Unit为。You can also use the UnitConverter class to convert an object of another data type to a Unit.

备注

此转换器只能将字符串转换为Unit字符串Unit , 并将转换为字符串。This converter can convert only a string to Unit and a Unit to a string.

注意

永远不应直接访问类型转换器。You should never access a type converter directly. 改为使用System.ComponentModel.TypeDescriptor调用适当的转换器。Instead, call the appropriate converter by using System.ComponentModel.TypeDescriptor. 有关详细信息, 请参阅System.ComponentModel.TypeConverter基类中的示例。For more information, see the examples in the System.ComponentModel.TypeConverter base class.
