Visual C# - 将文本框的内容写入 .txt 文件 [英] Visual C# - Write contents of a textbox to a .txt file

问题描述

我正在尝试使用 Visual C# 将文本框的内容保存到文本文件中.我使用以下代码:

I'm trying to save the contents of a textbox to a text file using Visual C#. I use the following code:

private void savelog_Click(object sender, EventArgs e)
    {
        if (folderBrowserDialog3save.ShowDialog() == DialogResult.OK)
        {
            // create a writer and open the file
            TextWriter tw = new StreamWriter(folderBrowserDialog3save.SelectedPath + "logfile1.txt");
            // write a line of text to the file
            tw.WriteLine(logfiletextbox);
            // close the stream
            tw.Close();
            MessageBox.Show("Saved to " + folderBrowserDialog3save.SelectedPath + "\logfile.txt", "Saved Log File", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }
    }

但我只在文本文件中得到以下文本行:

but I only get the following line of text in the textfile:

System.Windows.Forms.TextBox, Text: 

紧随其后的是文本框中实际内容的一小部分，以..."结尾.为什么不写文本框的全部内容?

Followed by only a short portion of what was actually in the textbox, ended with '...'. Why doesn't it write the entire contents of the textbox?

推荐答案

在这种情况下，真的不需要使用 TextWriter.

Using the TextWriter isn't really necessary in this case.

File.WriteAllText(filename, logfiletextbox.Text) 

更简单.您可以将 TextWriter 用于需要长时间保持打开状态的文件.

is simpler. You'd use TextWriter for a file you need to keep open for a longer period of time.
