显示错误

引发异常：Runtime.exe中的“ System.IndexOutOfRangeException”。Runtime.exe中发生了类型为“ System.IndexOutOfRangeException”的未处理异常。索引超出了数组的范围。

程序“ [7172] Runtime.exe”已退出，代码为-1（0xffffffff）。

第25行错误System.IndexOutOfRangeException：'索引在数组的边界之外。'

乍一看，我会说args[]不包含任何元素或仅包含1个元素。 您应该先添加支票，然后再访问它。

if (args == null)
{
    if (args.Length > 0) // or for your specific case: (args.Length >= 2)
        //do your stuff (including further appropriate checks)
}
