推荐答案

我们怎么知道?


在没有上下文的情况下仅提供半行代码，并且没有其他任何有说服力的线索将无济于事.

还有更多的东西了吗?或者您的智商在这一点上摇摆不定.


在这里给我们扔个骨头！

How can we tell?


Providing half a line of code, out of context and with no other tell-tale clues will not help.

Is there any more of it, or has your intellisense thrown a wobbly at that point.


Throw us a bone here!

有关MSDN的完整详细信息:
例如

Full details are on MSDN: String.Format method[^]

But in essence, String.Format takes a variable number of parameters (one or more) and returns a string made up from the various parts you give it.
It you pass it two or more parameters, the first one must be a string, and controls how the others are used. If any part of the string is enclosed in ''{'' and ''}'' then it refers to the other parameters, and will be substituted. Normally, the contents of the ''{'' and ''}'' pair is a numeric refenece by parameter number, satrtign from zero, but it can also contain formatting information for that parameter.

For example

String.Format("EXEC {0} /INDEX={1}", "ProgramName", 123);

将返回一个字符串:

"EXEC ProgramName /INDEX=123"

我认为他正在询问{1}

在这种情况下，请查看 String.Format方法(字符串，对象) [ ^ ]

希望对您有帮助

I think he''s asking about the {1}

If that''s the case, then take a look at the String.Format Method (String, Object)[^]

Hope it helps
