如何从一个文本文件读取然后在一个控制台应用程序中写入另一个文件？

阿拉默·阿什拉夫（AlameerAshraf）

 static void Main(string[] args)
    {


        FileInfo fileInfo = new FileInfo("C:\\Users\\Alameer Ashraf\\Desktop\\data binding and I Ostreaming\\ResultFile.txt");
        using (StreamWriter writer = fileInfo.CreateText())
        {
            FileInfo Teto = new FileInfo("C:\\Users\\Alameer Ashraf\\Desktop\\data binding and I Ostreaming\\WorkerTable.txt");
            foreach (string line in File.ReadLines("C:\\Users\\Alameer Ashraf\\Desktop\\data binding and I Ostreaming\\WorkerTable.txt"))
            {

                string[] columns = line.Split(',');

                Console.WriteLine("<Name>");
                Console.WriteLine(columns[0]);
                Console.WriteLine("<" + "/" + "Name" + ">");

                Console.WriteLine("<ID >");
                Console.WriteLine(columns[1]);
                Console.WriteLine("<" + "/" + "ID " + ">");

                Console.WriteLine("<Number>");
                Console.WriteLine(columns[2]);
                Console.WriteLine("<" + "/" + "Number " + ">");

                Console.WriteLine("<Job>");
                Console.WriteLine(columns[3]);
                Console.WriteLine("<" + "/" + "Job " + ">");
            }
            Console.ReadLine();
        }

我没有做我已经解释过的事情？请帮忙，我想从一个文件中读取内容，然后使用相同的应用程序将我正在读取的内容写入另一个文件中，我可以这样做吗？我想读取一个.csv文件并从中提取信息，然后使用IO File流将该信息重写为同一控制台应用程序中的另一个文本文件。

以下代码将执行您想要的操作：

class Program
{
        static void Main(string[] args)
        {
            using(StreamReader reader = new StreamReader(File.OpenRead("C:\\Users\\Alameer Ashraf\\Desktop\\data binding and I Ostreaming\\WorkerTable.txt")))
            {
                using (StreamWriter writer = new StreamWriter(File.Open ("C:\\Users\\Alameer Ashraf\\Desktop\\data binding and I Ostreaming\\ResultFile.txt", FileMode.Create)))
                { 
                    string line;
                    while((line = reader.ReadLine()) != null) {
                        string[] columns = line.Split(',');

                        WriteAndPrint(writer, "<Name>");
                        WriteAndPrint(writer, columns[0]);
                        WriteAndPrint(writer, "</Name>");

                        WriteAndPrint(writer, "<ID >");
                        WriteAndPrint(writer, columns[1]);
                        WriteAndPrint(writer, "</ID >");

                        WriteAndPrint(writer, "<Number>");
                        WriteAndPrint(writer, columns[2]);
                        WriteAndPrint(writer, "</Number>");

                        WriteAndPrint(writer, "<Job>");
                        WriteAndPrint(writer, columns[3]);
                        WriteAndPrint(writer, "</Job>");
                    }
                }
            }
            Console.ReadLine();
        }

        static void WriteAndPrint(StreamWriter writer, string line)
        {
                Console.WriteLine(line);
                writer.WriteLine(line);
        }
    }

虽然，当.NET中存在一个用于与XML数据进行交互的非常好的库时，我不愿看到将XML直接写入文件的情况。您可能还应该寻找合适的CSV解析器，或者自己编写一个。这不是一个很难匹配的规范。
