## 拷贝文件并判断是否成功

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));
```

判断参数个数 myapp foo bar ：

shell ：
2 * -> foo bar
$0 -> myapp
$1 -> foo
$2 -> bar

bat：
%* -> foo bar
%0 -> myapp
%1 -> foo
%2 -> bar

set argC=0
for %%x in (%*) do Set /A argC+=1

echo %argC%
