Question

我遇到了保存当前打开的文件的问题，而没有弹出对话框询问保存它的名称。

为了更清楚地说明一下，我打开一个.txt文件并使用它，然后只想点击“保存”并保存文件而不弹出“另存为”对话框。

这是我的保存代码：

       private void SaveFile()
    {
        SaveFileDialog fileChooser = new SaveFileDialog();
        fileChooser.Title = "Choose Save Location";
        fileChooser.Filter = "Text Files (*.txt)|*.txt";

        fileChooser.OverwritePrompt = false; //Removes warning

        DialogResult result = fileChooser.ShowDialog();

        if (result == DialogResult.Cancel)
        {
            return;
        }

        try
        {
            string fileName = fileChooser.FileName;
            output = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.Write);

            fileWriter = new StreamWriter(output);

            foreach (Employee emp in employee)
            {
                fileWriter.WriteLine(emp.Firstname + "," + emp.Lastname + "," + emp.Position + "," + emp.Bmonth + "," + emp.Bday + "," + emp.BYear + "," + emp.Salary + "," + emp.Hiremonth + "," + emp.Hireday + "," + emp.Hireyear);
            }

            fileWriter.Close();
            output.Close();

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
        finally
        {
            fileWriter.Close();
            output.Close();
        }
    }

只要将它保存到.txt文件并重新加载，一切都很有效，只是那个让我烦恼的弹出窗口。

Answer 1

fileChooser对象是SaveFileDialog对象。你通过调用它来显示它：

DialogResult result = fileChooser.ShowDialog();

如果您不想显示对话框，只需省略fileChooser代码，然后使用：

string fileName = strAlreadyKnownFileName;

Answer 2

我首先在一些变量中保存已打开文件的完整路径，然后说：

private string filepath = "path/to/my/file";

然后你需要创建一个按钮并调用它，即“保存”双击按钮并编写这个简单的代码，以保存你想要的当前打开的文件：

就这么简单......

编辑：

private void SaveFile()
{
   //do your loop and stuff in here and finally write your text to the file using this
   File.WriteAllText(filepath, yourtexttobesaved);
}

保存当前打开的文件而不提示
