提问by user2144293
I`m getting an ArgumentException from the following code:
我从以下代码中得到一个 ArgumentException：
string strPath="C:\somename.xls";
startPath=System.IO.Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
filePath = System.IO.Path.Combine(startPath, strPath);
I found this code on Stack Overflow. Link: C#:Copy protected worksheet to another excel fileI don't exactly know what it is. Please tell me what it is. This code I'm building into an exe.
我在 Stack Overflow 上找到了这段代码。链接： C#:Copy protected worksheet to another excel file我不知道它是什么。请告诉我它是什么。这段代码我正在构建到一个 exe 中。
Lastly, I need to Copy one worksheet to another file.
最后，我需要将一个工作表复制到另一个文件。
What`s wrong am I doing? I deploy this in server.
我怎么了？我在服务器中部署它。

what that code appears to do, is it gets your working directory(wherever the exeassociated with your code is), and combines it with "C:\\somename.xls"(which doesn't make sense.)
该代码似乎在做什么，它获取您的工作目录（exe与您的代码相关联的任何位置），并将其与"C:\\somename.xls"（这没有意义。）
I think you might have intended something like
我想你可能有这样的打算
string strPath=@"somename.xls";
so assume you're running your application from
所以假设你正在运行你的应用程序
"C:\Users\owner\documents\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\bin\Debug"
what that code would do is set filePathto
该代码将执行的操作设置filePath为
"C:\Users\owner\documents\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\bin\Debug\somename.xls"
the first thing I saw was
我看到的第一件事是
string filePath="C:\somename.xls";
\is a special character, for determining other characters. for instance '\n'is a newline. '\\'is the actual backslash.
\是一个特殊字符，用于确定其他字符。例如'\n'是一个换行符。 '\\'是实际的反斜杠。
so, you want to escape your \with another \
所以，你想\和另一个人一起逃离\
string filePath="C:\somename.xls";
or make it a literal string by putting a @in front of it.
或者通过@在它前面放一个来使它成为一个文字字符串。
string filePath=@"C:\somename.xls";

Your code should be:
你的代码应该是：
string filePath = "C:\somename.xls"
You need double backslashes.
你需要双反斜杠。

Two problems with the code,
代码有两个问题，
First
第一的
string filePath="C:\somename.xls";
\is a special character, for determining other characters. for instance '\n'is a newline. '\\'is the actual backslash.
\是一个特殊字符，用于确定其他字符。例如'\n'是一个换行符。 '\\'是实际的反斜杠。
Second
第二
filePathcontains a root path, C:\\. Path.Combinewill just return filePaththen, it cannot be combined.
filePath包含一个根路径，C:\\。 Path.Combine届时将返回filePath，无法合并。

Your main problem is in startPathparameter.
您的主要问题在于startPath参数。
System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName
If you trace your code, in FileNameyou will see a bad symbol character witch is illegal
如果你跟踪你的代码，FileName你会看到一个坏符号字符女巫是非法的
