如何从文本文件中获取值并在文本框中设置它们

本文关键字：文本 设置 获取 文件 | 更新日期: 2023-09-27 17:52:50

问题来了:我有两个类。表单1创建了一个.txt- file并在其中设置了两个值(string)。现在我想通过按下按钮(bdireckt)来获得这两个字符串，并在表单2的文本框中设置每个字符串。

表格1(据我所知应该是正确的，但如果我错了，请告诉我):

    public void Txfw()
    {
        string txBetrag = gBetrag.Text;
        string txMonate = gMonate.Text;
        string[] vars = new string[] { txBetrag, txMonate };
        using (StreamWriter sw = new StreamWriter(@"C:'Users'p2'Desktop'variablen.txt"))
        {
            foreach (string s in vars)
            {
                sw.WriteLine(s);
            }
        }
    }

表格二(不知道如何进行):

    private void bDirekt_Click(object sender, RoutedEventArgs e)
    {
        using (StreamReader sr = new StreamReader("variables.txt")) ;
        string line = "";
        while ((line = sr.ReadLine()) != null)
        {
            monate2.Text = 
        }
    }

我非常感谢你的帮助。

试试这个

StringBuilder sb = new StringBuilder();
    using (StreamReader sr = new StreamReader(@"C:'Users'p2'Desktop'variablen.txt"))
   {
                   string line;
                   // Read and display lines from the file until 
                   // the end of the file is reached. 
                   while ((line = sr.ReadLine()) != null)
                   {
                      sb.Append((line);
                   }
    }
    monate2.Text = sb.Tostring();

UPDATE:要将第一行与其余文本分开，您可以尝试这样做。总有更好的方法来实现这一点。

StringBuilder sb = new StringBuilder();
    string headerLine = string.Empty;
    int currentLine = 0;
        using (StreamReader sr = new StreamReader(@"C:'Users'p2'Desktop'variablen.txt"))
       {
                       string line;
                       // Read and display lines from the file until 
                       // the end of the file is reached. 
                       while ((line = sr.ReadLine()) != null)
                       {
                          currentLine++; //increment to keep track of current line number.
                          if(currentLine == 1)
                          {
                            headerLine = line;
                            continue; //skips rest of the processing and goes to next line in while loop
                          }
                          sb.Append((line);
                       }
        }
        header.Text = headerLine;
        monate2.Text = sb.ToString();
