保存时设置超时

保存时设置超时

Aspose.CAD for .NET API 允许您在保存时设置超时。这在保存过程耗时较长或消耗内存较多的情况下可能会很有帮助。为此，API 提供了 InterruptionTokenSource 类。 InterruptionTokenSource 类提供一个用于中断长时间操作的令牌。

示例代码

以下代码片段演示了 InterruptionTokenSource 类的使用。

// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-.NET
string SourceDir = RunExamples.GetDataDir_DWGDrawings();
string OutputDir = RunExamples.GetDataDir_Output();

using (Image cadDrawing = Image.Load(SourceDir + "Drawing11.dwg"))
{
    var rasterizationOptions = new CadRasterizationOptions();

    rasterizationOptions.PageWidth = cadDrawing.Size.Width;
    rasterizationOptions.PageHeight = cadDrawing.Size.Height;

    using (var its = new InterruptionTokenSource())
    {
        PdfOptions CADf = new PdfOptions();
        CADf.VectorRasterizationOptions = rasterizationOptions;
        CADf.InterruptionToken = its.Token;

        var exportTask = Task.Factory.StartNew(() =>
        {
            cadDrawing.Save(OutputDir + "PutTimeoutOnSave_out.pdf", CADf);
        });

        Thread.Sleep(10000);
        its.Interrupt();

        exportTask.Wait();
    }
}
