我想显示一个消息框，并在程序只是继续不待我点击此消息框确定。 能不能做到？
else
{
// Debug or messagebox the line that fails
MessageBox.Show("Cols:" + _columns.Length.ToString() + " Line: " + lines[i]);
}
Answer 1:
首先，正确的解决办法是更换一个平面窗口在MessageBox（或形成，如果您使用的WinForms）。 这将是相当简单的。 实施例（WPF）
<Window x:Class="local:MyWindow" ...>
<Grid>
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center"
Text="{Binding}" />
<Button HorizontalAlignment="Right" VerticalAlignment="Bottom"
Click="SelfClose">Close</Button>
</Grid>
</Window>
...
class MyWindow : Window
{
public MyWindow(string message) { this.DataContext = message; }
void SelfClose(object sender, RoutedEventArgs e) { this.Close(); }
}
...
new MyWindow("Cols:" + _columns.Length.ToString() + " Line: " + lines[i]).Show();
如果你想快速和肮脏的解决方案，你可以调用从暴殄天物线程的消息框：
Thread t = new Thread(() => MessageBox("lalalalala"));
t.SetApartmentState(ApartmentState.STA);
t.Start();
（不知道ApartmentState.STA实际需要）
Answer 2:
//You need to add this if you don't already have it
using System.Threading.Tasks;
//然后这里是你的代码，将异步运行的主线程的;
Task.Factory.StartNew( () =>
{
MessageBox.Show("This is a message");
});
Answer 3:
用这个
this.Dispatcher.BeginInvoke(new Action(() => { MessageBox.Show(this, "text"); }));
希望能帮助到你。
Answer 4:
using System.Threading;
static void MessageThread()
{
MessageBox.Show("Cols:" + _columns.Length.ToString() + " Line: " + lines[i]);
}
static void MyProgram()
{
Thread t = new Thread(new ThreadStart(MessageThread));
t.Start();
}
这将开始在它自己的线程MessageThread功能，使你的代码在我所谓休息MyProgram可以继续。
希望这可以帮助。
Answer 5:
你想要什么是模式窗体。 这里有一些资料和样品给你。
Answer 6:
你需要使用多线程来实现这一任务，其中一个线程（主线程）会做加工等将被用于显示消息框。
Answer 7:
你也可以考虑使用委托。
下面snippits来自财产以后我刚刚完成： -
namespace YourApp
{
public partial class frmMain : Form
{
// Declare delegate for summary box, frees main thread from dreaded OK click
private delegate void ShowSummaryDelegate();
ShowSummaryDelegate ShowSummary;
/// <summary>
/// Your message box, edit as needed
/// </summary>
private void fxnShowSummary()
{
string msg;
msg = "TEST SEQUENCE COMPLETE\r\n\r\n";
msg += "Number of tests performed: " + lblTestCount.Text + Environment.NewLine;
msg += "Number of false positives: " + lblFalsePve.Text + Environment.NewLine;
msg += "Number of false negatives: " + lblFalseNve.Text + Environment.NewLine;
MessageBox.Show(msg);
}
/// <summary>
/// This callback is used to cleanup the invokation of the summary delegate.
/// </summary>
private void fxnShowSummaryCallback(IAsyncResult ar)
{
try
{
ShowSummary.EndInvoke(ar);
}
catch
{
}
}
/// <summary>
/// Your bit of code that wants to call a message box
/// </summary>
private void tmrAction_Tick(object sender, EventArgs e)
{
ShowSummary = new ShowSummaryDelegate(fxnShowSummary);
AsyncCallback SummaryCallback = new AsyncCallback(fxnShowSummaryCallback);
IAsyncResult SummaryResult = ShowSummary.BeginInvoke(SummaryCallback, null);
}
// End of Main Class
}
}
