namespace CosmosKernel2
{
    public class Kernel : Sys.Kernel
    {
        protected override void BeforeRun()
        {
           Console.WriteLine("hi.");
        }
        protected override void Run()
        {
            Console.WriteLine("Input:");
            String input = Console.ReadLine();
        if (input.StartsWith("echo"))
            {
               var index = input.LastIndexOf(input);  // ERROR HERE
               Console.WriteLine("echo: " + input.Substring(cmdLastIndex));
            }}}}

我正在制作一个简单的操作系统来响应用户的输入。然而，我得到一些错误。我认为创建var索引和存储最后一个索引没有什么错。

这是我的错误:

Var并存储错误的最后索引

看起来您指的是未定义的变量cmdLastIndex。你应该把它重命名为index。

Console.WriteLine("echo: " + input.Substring(cmdLastIndex));
