期待c＃程序中的标识符错误 [英] expecting identifier error in c# program

问题描述

using System;
using System.Text;
public class run_length_encoding
{
public static string encode(string source)
{
StringBuilder dest = new StringBuilder();
for (int i = 0; i < source.Length; i++)
{
int runLength = 1;
while (i + 1 < source.Length && source[i] == source[i + 1])
{
runLength++;
i++;
}
dest.Append(runLength);
dest.Append(source[i]);
}
return dest.ToString();
}
public static void Main(string[] args)
{
Scanner scn = new Scanner{System.in};
Console.WriteLine("Input string");
string source = scn.next();
Console.WriteLine("Output " + encode(source));
}
}

error:
prog.cs(23,33): error CS1526: Unexpected symbol `in', expecting `identifier

推荐答案

引用：

扫描程序scn = new Scanner {System.in};

Scanner scn = new Scanner{System.in};

.NET中没有 System.in 框架（据我所知，没有这样的 Scanner 类）。你有没有机会切掉'Java'代码？

There is no System.in in the .NET framework (and there is not such a Scanner class, as far as I know). Have you cut'n'pasted Java code, by chance?
