If it's going on argis The secondary development was not carried out mapcontrol Control initialization , We often encounter inexplicable problems , For example, reading raster data and flashing back , Failed to create database , Layers with custom coordinate system or unknown coordinate system cannot be read , The solution is as follows ：

cs

When the main program is initialized, add the following code ：

private void Initial()
{
    
    var win = new Window()
    {
    
        Content = new WindowsFormsHost() {
     Child = new AxMapControl() },
        WindowState = WindowState.Minimized
    };
    win.Loaded += (s, e) =>
    {
    
        var host = ((Window)s).Content as WindowsFormsHost;
        host.Child.Dispose();
        host.Dispose();
        ((Window)s).Close();
    };
    win.Show();
    
}
