我有一个保存/加载 XML 文件的 Windows 窗体,它会询问用户他们想在哪里保存/加载它。我的问题是我不知道如何更改此方法以从用户想要的位置加载文件,而不是从流读取器指定的位置加载文件。
下面的代码是我的按钮和 LoadValues 方法。
private void Edittask_loadbuttonClick(
object sender, EventArgs e)
{
Stream myStream = null;
var sFile1 = new OpenFileDialog();
sFile1.InitialDirectory = "c:\\";
sFile1.Filter = "xml files (*.xml)|*.xml";
sFile1.FilterIndex = 2;
sFile1.RestoreDirectory = true;
if (sFile1.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = sFile1.OpenFile()) != null)
{
using (myStream)
{
var v = LoadValues();
this.load_task1_name.Text =
v.task1_name;
this.load_task1_desc.Text =
v.task1_desc;
this.load_task1_date.Value =
v.task1_date;
this.load_checkbox.Checked =
v.task1_checkbox;
}
}
}
catch (Exception ex)
{
MessageBox.Show(
"Error: Could not read file from disk. Original error: " +
ex.Message);
}
}
}
public Values LoadValues()
{
var serializer = new XmlSerializer(typeof (Values));
using (
TextReader textReader = new StreamReader(
"E:\\hello.xml")
)
{
return
(Values) serializer.Deserialize(textReader);
}
}
