的Visual C＃ - 写一个文本框的内容为.txt文件 [英] Visual C# - Write contents of a textbox to a .txt file

问题描述

我想一个文本框的内容保存到使用Visual C＃的文本文件。我用下面的代码：

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);
        }
    }

但我只让文字在下面一行文本文件：

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

System.Windows.Forms.TextBox, Text: 

其次是究竟是在文本框中，以结束只有短短的一部分...。为什么不把它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

使用的TextWriter是不是真的有必要在这种情况下。

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

File.WriteAllText(filename, logfiletextbox.Text) 

更简单。你会使用的TextWriter你需要保持开放的时间较长时期的文件。

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