Equivalence of "With...End With" in C#?
提问by odiseh
I know that C# has the usingkeyword, but usingdisposes of the object automatically.
我知道 C# 有using关键字，但会using自动处理对象。

C# doesn't have an equivalent language construct for that.
C# 没有对应的语言结构。

It's not equivalent, but would this syntax work for you?
它不是等价的，但是这种语法对你有用吗？
Animal a = new Animal()
{
SpeciesName = "Lion",
IsHairy = true,
NumberOfLegs = 4
};

I think the equivalent of the following VB:
我认为相当于以下VB：
With SomeObjectExpression()
.SomeProperty = 5
.SomeOtherProperty = "Hello"
End With
Would be this is C#:
这将是C#：
{
Var q=SomeOtherExpression();
q.SomeProperty = 5;
q.SomeOtherProperty = "Hello";
}
The only real difference is that in vb, the identifier doesn't have a name "q", but is simply a default identifier used when a period is encountered without any other identifier before it.
唯一真正的区别是在 vb 中，标识符没有名称“q”，而只是遇到句点时使用的默认标识符，而在它之前没有任何其他标识符。

There is no equivalent, but I think discussing a syntax might be interesting!
没有等价物，但我认为讨论语法可能很有趣！
I quite like;
我相当喜欢;
NameSpace.MyObject.
{
active = true;
bgcol = Color.Red;
}
Any other suggestions?
还有其他建议吗？
I cant imagine that adding this language feature would be difficult, essentially just a preprocessed.
我无法想象添加这个语言特性会很困难，本质上只是一个预处理。
EDIT:
编辑：
I was sick of waiting for this feature, so here is and extension that achieves a similar behavior.
我厌倦了等待这个功能，所以这里是实现类似行为的扩展。
/// <summary>
/// C# implementation of Visual Basics With statement
/// </summary>
public static void With<T>(this T _object, Action<T> _action)
{
_action(_object);
}
Usage;
用法;
LongInstanceOfPersonVariableName.With(x => {
x.AgeIntVar = 21;
x.NameStrVar = "John";
x.NameStrVar += " Smith";
//etc..
});
EDIT:Interestingly it seems someone beat me to the punch, again, with this "solution". Oh well..
编辑：有趣的是，似乎有人再次用这个“解决方案”击败了我。那好吧..
