private void ReloadForm()
{
comboBox4.ResetText();
}
private void button2_Click(object sender, EventArgs e)
{
string layers = textBox1.Text;
FileStream fs = new FileStream("xml/" + layers + ".xml", FileMode.Create);
XmlWriter w = XmlWriter.Create(fs);
w.WriteStartDocument();
w.WriteStartElement("layers");
// Write a product.
w.WriteStartElement("layer");
w.WriteAttributeString("id", "1");
w.WriteElementString("layerName", layers);
w.WriteEndElement();
w.WriteEndDocument();
w.Flush();
fs.Close();
ReloadForm();
}
public Form3()
{
InitializeComponent();
// Put XML name files in comboBox4
string[] filePaths = Directory.GetFiles(@"xml'", "*");
foreach (string file in filePaths)
{
string mypath = file;
string[] directories = mypath.Split(Path.DirectorySeparatorChar);
foreach (string dir in directories){
comboBox4.Items.Add(dir);
}
}
}
上面的代码在单击时创建XML文件,我得到了显示每个XML文件名称的单独代码。我尝试使用void ReloadForm()
刷新 comboBox4 文本,但它失败了。
有什么想法可以解决这个问题吗?
将Form3
构造函数更改为此
public Form3()
{
InitializeComponent();
ReloadComboBox4();
}
并将ReloadForm()
重命名为 ReloadComboBox4
并将其更改为
private void ReloadComboBox4()
{
comboBox4.Items.Clear()
string[] filePaths = Directory.GetFiles(@"xml'", "*");
foreach (string file in filePaths)
{
string mypath = file;
string[] directories = mypath.Split(Path.DirectorySeparatorChar);
foreach (string dir in directories)
{
comboBox4.Items.Add(dir);
}
}
}
