Expression 构造函数

定义

命名空间:

System.Linq.Expressions

程序集:

System.Linq.Expressions.dll

程序集:

System.Core.dll

程序集:

netstandard.dll

构造 Expression 的新实例。

重载

Expression()	构造 Expression 的新实例。
Expression(ExpressionType, Type)	已过时。 已过时。 初始化 Expression 类的新实例。

Expression()

构造 Expression 的新实例。

protected:
 Expression();

protected Expression ();

Protected Sub New ()

Expression(ExpressionType, Type)

注意

use a different constructor that does not take ExpressionType. Then override NodeType and Type properties to provide the values that would be specified to this constructor.

注意

This constructor has been deprecated. Use a different constructor that does not take ExpressionType. Then override NodeType and Type properties to provide the values that would be specified to this constructor.

初始化 Expression 类的新实例。

protected:
 Expression(System::Linq::Expressions::ExpressionType nodeType, Type ^ type);
