什么是C＃相当于VB中的With语句？ [重复]

可能重复:c#中“With ... End With”的等价性?

There was one feature of VB that I really like...the With statement. Does C# have any equivalent to it? I know you can use using to not have to type a namespace, but it is limited to just that. In VB you could do this:

我真的很喜欢VB的一个特性...... With语句。 C#有任何等价物吗?我知道您可以使用using来不必键入命名空间,但它仅限于此。在VB中你可以这样做:

With Stuff.Elements.Foo
    .Name = "Bob Dylan"
    .Age = 68
    .Location = "On Tour"
    .IsCool = True
End With

The same code in C# would be:

C#中的相同代码是:

Stuff.Elements.Foo.Name = "Bob Dylan";
Stuff.Elements.Foo.Age = 68;
Stuff.Elements.Foo.Location = "On Tour";
Stuff.Elements.Foo.IsCool = true;

3 个解决方案

#1

Not really, you have to assign a variable. So

不是,你必须分配一个变量。所以

    var bar = Stuff.Elements.Foo;
    bar.Name = "Bob Dylan";
    bar.Age = 68;
    bar.Location = "On Tour";
    bar.IsCool = True;

Or in C# 3.0:

或者在C#3.0中:

    var bar = Stuff.Elements.Foo
    {
        Name = "Bob Dylan",
        Age = 68,
        Location = "On Tour",
        IsCool = True
    };

#2

Aside from object initializers (usable only in constructor calls), the best you can get is:

除了对象初始化器(仅在构造函数调用中可用)之外,您可以获得的最佳结果是:

var it = Stuff.Elements.Foo;
it.Name = "Bob Dylan";
it.Age = 68;
...

#3

The closest thing in C# 3.0, is that you can use a constructor to initialize properties:

C#3.0中最接近的是,您可以使用构造函数初始化属性:

Stuff.Elements.Foo foo = new Stuff.Elements.Foo() {Name = "Bob Dylan", Age = 68, Location = "On Tour", IsCool = true}
