将iostream输入代码从C++移植到C＃-PortingiostreaminputcodefromC++toC#

This is C++ code for reading traces of address of main memory for cache memory simulation:

这是用于读取主存储器地址跟踪的C ++代码,用于高速缓存存储器仿真:

 char hex[20];
 ifstream infile;
 infile.open(filename,ios::in);
 if(!infile) {
    cout<<"Error! File not found...";
    exit(0);
 }
 int set, tag, found;
 while(!infile.eof()) { //Reading each address from trace file
      if(base!=10) {
           infile>>hex;
           address = changebase(hex, base);
      } else {
           infile>>address;
      }
      set = (address / block_size) % no_set;
      tag  = address / (block_size * no_set);
 }

I have converted this to C# code:

我已将其转换为C#代码:

 char[] hex = new char[20];
 FileStream infile=new FileStream(filename, FileMode.Open);

 if (infile == null) {
     Console.Write("Error! File not found...");
     Environment.Exit(0);
 }
 int set;
 int tag;
 int found;
 while (!infile.CanRead) { //Reading each address from trace file
     if (@base != 10) {
         infile >> hex;
         address = changebase(hex, @base);
     } else {
         infile >> address;
     }
     set = (address / block_size) % no_set;
     tag = address / (block_size * no_set);
 }

The problem is on line infile >> hex; C# is giving syntax errors, as shift right operator cannot be applied to string operators.

问题是在线infile >> hex; C#给出语法错误,因为右移运算符不能应用于字符串运算符。

Why this is not working? I'm making a small cache hit and miss calculation project.

为什么这不起作用?我正在制作一个小缓存命中和错过计算项目。

std::cout <<"Hello" <

Console.WriteLine("Hello");

std::stringstream ss;
int age = 25;
ss <<"So you must be " <

StringBuilder sb = new StringBuilder();
int age = 25;
sb.Append("So you must be ").Append(age).Append(" years old");

sb.AppendFormat("So you must be {0} years old", age);
