Hi, I'm trying to use a progress bar to show the progress of my call to tool, but it doesn't show up no matter how I put it.
private async void Button_Click_import(object sender, RoutedEventArgs e)
{
AddlayertoDatabase(); // 添加选中图层
//var progsrc=new CancelableProgressorSource(progDlg);
var map = MapView.Active.Map;
var progDlg = new ProgressDialog("进度条", "取消", 100, true);
progDlg.Show();
// 创建一个图层组
GroupLayer groupLayer = null;
await QueuedTask.Run(() =>
{
// 创建图层组
groupLayer = LayerFactory.Instance.CreateGroupLayer(map, 0, "表面模型");
});
foreach (FeatureLayer selectedLayer in _selectedLayers)
{
var fcName = selectedLayer.Name;
var fieldName = comboBox2.Text;
var gdbPath = Project.Current.DefaultGeodatabasePath;
var outputdata = System.IO.Path.Combine(gdbPath, $"{fcName}_表面模型");
await QueuedTask.Run(async () =>
{
try
{
// 构建工具箱工具的参数
var parameters = Geoprocessing.MakeValueArray(
fcName,
fieldName,
outputdata,
"MAXIMUM",
null,
cellsize
);
// 执行工具
var progsrc=new CancelableProgressorSource(progDlg);
//var environments = Geoprocessing.MakeEnvironmentArray(overwriteoutput: true);
GPExecuteToolFlags executeFlags = GPExecuteToolFlags.GPThread | GPExecuteToolFlags.AddToHistory | GPExecuteToolFlags.RefreshProjectItems;
var results = await Geoprocessing.ExecuteToolAsync("conversion.PointToRaster", parameters, null, progsrc.CancellationTokenSource.Token, null, executeFlags);
// 处理结果
// 获取错误信息
if (results.IsFailed)
{
await QueuedTask.Run(() =>
{
Geoprocessing.ShowMessageBox(results.Messages, "工具执行失败", GPMessageBoxStyle.Error);
});
}
else
{
//MessageBox.Show("工具执行成功！");
await QueuedTask.Run(() =>
{
var rasterLayer = LayerFactory.Instance.CreateLayer(new Uri(outputdata), groupLayer) as RasterLayer;
});
}
}
catch (Exception ex)
{
await QueuedTask.Run(() =>
{
//System.Windows.MessageBox.Show($"发生错误：{ex.Message}");
System.Diagnostics.Debug.WriteLine($"发生错误：{ex.Message}");
System.Diagnostics.Debug.WriteLine($"StackTrace: {ex.StackTrace}");
});
}
});
}
progDlg.Hide();
}
