protected:
 Expression(System::Linq::Expressions::ExpressionType nodeType, Type ^ type);
protected Expression(System.Linq.Expressions.ExpressionType nodeType, Type type);
[System.Obsolete("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.")]
protected Expression(System.Linq.Expressions.ExpressionType nodeType, Type type);
new System.Linq.Expressions.Expression : System.Linq.Expressions.ExpressionType * Type -> System.Linq.Expressions.Expression
[<System.Obsolete("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.")>]
new System.Linq.Expressions.Expression : System.Linq.Expressions.ExpressionType * Type -> System.Linq.Expressions.Expression
Protected Sub New (nodeType As ExpressionType, type As Type)

参数
