VS2012或者VS2013面向win8开发的代码，
System.IO中没有File类没有
怎么写文件？有没有高手指点！

[上海什么大学]

一直都用FileStream+StreamReader或StreamWriter

[wind_cloud2011]

 string path = Path.GetTempFileName();
        FileInfo fi1 = new FileInfo(path);

        //Create a file to write to.
        using (StreamWriter sw = fi1.CreateText()) 
        {
            sw.WriteLine("Hello");
            sw.WriteLine("And");
            sw.WriteLine("Welcome");
        }	

        //Open the file to read from.
        using (StreamReader sr = fi1.OpenText()) 
        {
            string s = "";
            while ((s = sr.ReadLine()) != null) 
            {
                Console.WriteLine(s);
            }
        }

        try 
        {
            string path2 = Path.GetTempFileName();
            FileInfo fi2 = new FileInfo(path2);

            //Ensure that the target does not exist.
            fi2.Delete();

            //Copy the file.
            fi1.CopyTo(path2);
            Console.WriteLine("{0} was copied to {1}.", path, path2);

            //Delete the newly created file.
            fi2.Delete();
            Console.WriteLine("{0} was successfully deleted.", path2);

        } 
        catch (Exception e) 
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }

FileOpen(1, "E:\y.txt", OpenMode.Output) PrintLine(1, "abc") PrintLine(1, "123") FileClose(1)

和VB2008在win7下是一样的

加入IO包就行 using System.IO;
