System.IO.IOException：'该进程无法访问文件'@ .txt'，因为它正在被另一个进程使用。 [英] System.IO.IOException: 'The process cannot access the file '@.txt' because it is being used by another process.'

问题描述

我是编程新手，我有一个问题。如果我有两个功能，一个创建一个文本文件并将其写入，另一个打开同一个文本文件并从中读取。

我得到的错误是：

System.IO.IOException：'该进程无法访问文件'@ .txt'
，因为它正在被文件使用

我尝试为每个功能设置单独的计时器，但仍然无法正常工作。我认为最好的方法是函数2直到函数1结束才开始。
非常感谢！

 timerButtona1.Elapsed + = new ElapsedEventHandler（tickTimera1）; 
 timerButtona1.Interval = 3003; 
 timerButtona1.Enabled = true; 
}

 GET（linki [x]，fileNames [x]）; 
 //System.Threading.Thread.Sleep(6000）; 
} 
} 
 
异步void GET（字符串链接，字符串fileName）{
 var ODGOVOR =等待PRENOS_PODATKOV.GetStringAsync（link）; 
 File.WriteAllText（@ C：\Users\ ... \ + fileName + .txt，ODGOVOR）; 
} 
 
 void function2（）{
 string originalText = File.ReadAllText（@ C：\Users\ ... \fileName.txt，编码。默认）; 
动态modifiedText = JsonConvert.DeserializeObject（originalText）; 
 //然后我从相同的文本文件中读取并使用其中的一些数据。
} 
  

解决方案

编辑后必须关闭文件。

  var myFile = File.Create（myPath）; 
 // myPath = C：\file.txt 
 myFile.Close（）; 
 //关闭文本文件，例如file.txt 
 //您可以立即编写阅读功能。.
  

关闭后您可以再次使用它（供阅读）

I am new to programming and I have a question. If I have two functions, one creates a text file and writes into it, while the other opens the same text file and reads from it.

The error I get is:

System.IO.IOException: 'The process cannot access the file '@.txt' because it is being used by another process.'

I have tried setting seperate timers to each of the functions but it still does not work. I think the best way would be that the function two does not start until function one ends.

Can you help me achieve this? Thank you very much! Mike

Source code:

public Form1() {
    InitializeComponent();
    System.Timers.Timer timerButtona1 = new System.Timers.Timer();
    timerButtona1.Elapsed += new ElapsedEventHandler(tickTimera1);
    timerButtona1.Interval = 3003;
    timerButtona1.Enabled = true;
}

private async void tickTimera1(object source, ElapsedEventArgs e) {
    function1();
    function2();
}

void function1() {
    List<string> linki = new List<string>();

    linki.Add("https://link1.net/");
    linki.Add("https://link2.net/");
    linki.Add("https://link3.net/");

    List<string> fileNames = new List<string>();

    fileNames.Add("name1");
    fileNames.Add("name2");
    fileNames.Add("name3");

    for (int x = 0; x < fileNames.Count; x++) {
        GET(linki[x], fileNames[x]);
        //System.Threading.Thread.Sleep(6000);
    }
}

async void GET(string link, string fileName) {
    var ODGOVOR = await PRENOS_PODATKOV.GetStringAsync(link);
    File.WriteAllText(@"C:\Users\...\" + fileName + ".txt", ODGOVOR);
}

void function2() {
    string originalText = File.ReadAllText(@"C:\Users\...\fileName.txt", Encoding.Default);
    dynamic modifiedText = JsonConvert.DeserializeObject(originalText);
    //then i then i read from the same text files and use some data from it..
}

解决方案

You will have to close the file after editing it.

var myFile = File.Create(myPath);
//myPath = "C:\file.txt"
myFile.Close();
//closes the text file for eg. file.txt
//You can write your reading functions now..

After closing it you can again use it(for reading)
