Similar to Pass in Python for C#
提问by
In python we can ...
在python中，我们可以...
a = 5
if a == 5:
pass #Do Nothing
else:
print "Hello World"
Is there a similar way to do this in C#?
在 C# 中是否有类似的方法可以做到这一点？
回答by Lo?c Wolff
Use empty braces.
使用空大括号。
int a = 5;
if (a == 5) {}
else {
Console.Write("Hello World");
}

Empty block:
空块：
{}
回答by Ali
Why not just say:
为什么不直接说：
if (a != 5)
{
Console.Write("Hello World");
}
回答by Jon Skeet
Either use an empty block as suggested in other answers, or reverse the condition:
按照其他答案中的建议使用空块，或者反转条件：
if (a != 5)
{
Console.WriteLine("Hello world");
}
or more mechanically:
或更机械地：
if (!(a == 5))
{
Console.WriteLine("Hello world");
}

A better question would be why you would want to do such a thing. If you're not planning on doing anything then leave it out, rather.
一个更好的问题是你为什么想做这样的事情。如果你不打算做任何事情，那就把它排除在外。
int a = 5;
if (a != 5) {
Console.Write("Hello World");
}
回答by Kent Boogaart
Is passused in the context of a loop? If so, use the continuestatement:
是否pass在循环上下文中使用？如果是这样，请使用以下continue语句：
for (var i = 0; i < 10; ++i)
{
if (i == 5)
{
continue;
}
Console.WriteLine("Hello World");
}
回答by Umer
In case you don't want to use empty block, use
如果您不想使用空块，请使用
;
so the code should look like
所以代码应该看起来像
int a = 5;
if (a == 5)
;
else
{
Console.Write("Hello World");
}
although, code readability still suffer.
尽管如此，代码可读性仍然受到影响。
