Winform saveas文件位置

我想知道如何将winform中的文件保存到目标位置而不必在该位置进行硬编码。

现在,我的保存方法如下所示:

public void GenereateSettingsFile(List<Node> nodeList)
{
    string filePath = "Desktop\\Save.xml";
    _rootNode.RemoveChild(_userNode);

    _userNode = _xmlDoc.CreateElement("Display_Settings");
    _rootNode.AppendChild(_userNode);

    foreach (Node n in nodeList)
    {
        foreach (XmlElement e in n.GenerateXML(_xmlDoc))
        {

            _userNode.AppendChild(e);
        }
    }

    _xmlDoc.Save(filePath);
}

public void SaveXML(string location)
{
    _xmlDoc.Save(location);
}

当我按下保存按钮时调用它:

private void saveToolStripMenuItem_Click(object sender, EventArgs e)
{
    foo.GenereateSettingsFile(_nodeList);
}

现在,通过我的另存为功能,我已经得到了它,因此弹出一个新窗口,我可以浏览到我希望使用以下代码保存文件的位置:

private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
{
    using (SaveFileDialog dialog = new SaveFileDialog())
    {
        dialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
        dialog.FilterIndex = 2;
        dialog.RestoreDirectory = true;

        if (dialog.ShowDialog() == DialogResult.OK)
        {
            // Can use dialog.FileName
            using (Stream stream = dialog.OpenFile())
            {
                // Save data
                inmo.GenereateSettingsFile(_nodeList);
            }
        }
    }
}

但是,这仍然是调用我的旧保存功能,它告诉我的程序保存在桌面上。有没有办法可以将我保存的文件位置传递给我的保存功能?

尝试

dialog.InitialDirectory = myPreferredDirectory;

只需将filePath宣传为GenereateSettingsFile的参数。

private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
{
    using (SaveFileDialog dialog = new SaveFileDialog())
    {
        dialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
        dialog.FilterIndex = 2;
        dialog.RestoreDirectory = true;

        if (dialog.ShowDialog() == DialogResult.OK)
        {
            // Can use dialog.FileName
            //using (Stream stream = dialog.OpenFile())
            //{
            // Save data
            inmo.GenereateSettingsFile(_nodeList, dialog.FileName);
            //}
        }
    }
}

public void GenereateSettingsFile(List<Node> nodeList, string filePath)
{
    //string filePath = "Desktop\\Save.xml";
    _rootNode.RemoveChild(_userNode);

    _userNode = _xmlDoc.CreateElement("Display_Settings");
    _rootNode.AppendChild(_userNode);

    foreach (Node n in nodeList)
    {
        foreach (XmlElement e in n.GenerateXML(_xmlDoc))
        {

            _userNode.AppendChild(e);
        }
    }

    _xmlDoc.Save(filePath);
}
