我正在使用Windows应用程序，您可以在其中阻止和允许程序。我对如何调用comboboxitem有问题。 inc是组合框1内的一个项目，所有都是组合框2内的一个项目。我想创建一个条件，如果同时选择了两个comboboxitem，则运行该条件。我怎么做 ？谢谢
private void addSubmitBtn_Click(object sender, RoutedEventArgs e)
{
foreach (string path in pathT.Text.Split(';'))
if (File.Exists(path))
{
if ( inc.SelectedIndex > -1 && all.SelectedIndex > -1)
{
FWRule(path, NET_FW_RULE_DIRECTION_.NET_FW_RULE_DIR_IN, (blo.Checked) ? NET_FW_ACTION_.NET_FW_ACTION_BLOCK : NET_FW_ACTION_.NET_FW_ACTION_ALLOW, ((Control)sender).Tag.ToString());
}
if (outg.Checked || all.Checked)
{
FWRule(path, NET_FW_RULE_DIRECTION_.NET_FW_RULE_DIR_OUT, (blo.Checked) ? NET_FW_ACTION_.NET_FW_ACTION_BLOCK : NET_FW_ACTION_.NET_FW_ACTION_ALLOW, ((Control)sender).Tag.ToString());
}
}
((System.Windows.Controls.Panel)this.Parent).Children.Remove(this);
}
private void FWRule(string path, NET_FW_RULE_DIRECTION_ d, NET_FW_ACTION_ fwaction, string action)
{
try
{
INetFwRule firewallRule = (INetFwRule)Activator.CreateInstance(
Type.GetTypeFromProgID("HNetCfg.FWRule"));
firewallRule.Action = fwaction;
firewallRule.Enabled = true;
firewallRule.InterfaceTypes = "All";
firewallRule.ApplicationName = path;
firewallRule.Name = "PRST: " + System.IO.Path.GetFileName(path);
INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));
firewallRule.Direction = d;
if (action == "1") firewallPolicy.Rules.Add(firewallRule);
else
{
((System.Windows.Controls.Panel)this.Parent).Children.Remove(this);
}
}
catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message, "ERROR"); }
}
private void addCancelBtn_Click(object sender, RoutedEventArgs e)
{
((System.Windows.Controls.Panel)this.Parent).Children.Remove(this);
}
private void addBackBtn_Click(object sender, RoutedEventArgs e)
{
((System.Windows.Controls.Panel)this.Parent).Children.Remove(this);
}
private void pathT_TextChanged(object sender, TextChangedEventArgs e)
{
}
private void blo_CheckedChanged(object sender, EventArgs e)
{
}
private void al_CheckedChanged(object sender, EventArgs e)
{
}
private void Button_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog fd = new OpenFileDialog();
fd.Filter = "Executable|*.exe";
fd.Multiselect = true;
if (fd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
pathT.Text = String.Join(";", fd.FileNames);
}
}
}
}
这是XAML的一部分

最佳答案

可以选择组合框项目，但不能选中吗？您应该检查是否仅选中它们。除非您构建自己的控件，该控件具有可选中的复选框项的组合框
我认为我发现了您的问题，在您的if条件下，这种情况永远不会发生，因为inc和全部都是<ComboBox x:Name="Combobox1"的一部分，并且在您的代码中您说的是if ( inc.SelectedIndex > -1 && all.SelectedIndex > -1)不能同时选择这两个;）
例如，这应该起作用，因为它具有OR运算符if (outg.Checked || all.Checked)，因此应仅选择其中之一。
忽略以下部分，是一个解决方案，认为您正在使用Win Forms
您可以使用selectedIndexChanged
例如：
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
this.getValues(this.comboBox2, this.comboBox3);
}
private void comboBox3_SelectedIndexChanged(object sender, EventArgs e)
{
this.getValues(this.comboBox2, this.comboBox3);
}
public void compareValues(String value1, String value2)
{
if(value1.Equals("inc") && value2.Equals("all"))
{
this.runThis();
}
}
public void runThis()
{
//do your thing here :)
this.label1.Text = "run this!!!";
}
public void getValues(ComboBox cmb2, ComboBox cmb3)
{
String cmb1Value = "";
String cmb2Value = "";
try{
cmb1Value = this.comboBox2.SelectedItem.ToString();
}catch (Exception exception){
//not both set
}
try
{
cmb2Value = this.comboBox3.SelectedItem.ToString();
}catch (Exception exception){
//not both set
}
this.compareValues(cmb1Value, cmb2Value);
}
