System.Runtime.InteropServices.COMException:HRESULT:0x80040228 [英] System.Runtime.InteropServices.COMException: HRESULT:0x80040228

问题描述

我已经构建了一个Web服务，该服务将实现ArcTools中名为FeatureclassToCoverage的功能之一.我的代码如下:

I have built a webservice which is to realize one of the functions in ArcTools named FeatureclassToCoverage. My code is as below:

public string FeatureClassToCoverage(string string_inFeatures, string string_outCoverage) //List<string string_inFeatures>
   {
       IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
       IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(System.IO.Path.GetDirectoryName(string_inFeatures), 0);//<big>THE PROBLEM LINE</big>
       IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
       IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(System.IO.Path.GetFileNameWithoutExtension(string_inFeatures));

       String outDict = System.IO.Path.GetDirectoryName(string_inFeatures);
       String outCoverage = outDict + "\\" + string_outCoverage;

       ESRI.ArcGIS.ConversionTools.FeatureclassToCoverage featureClassToCoverage = new FeatureclassToCoverage(pFeatureClass, outCoverage);

       ESRI.ArcGIS.Geoprocessor.Geoprocessor gp = new Geoprocessor();
       ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult results = (ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult)gp.Execute(featureClassToCoverage, null);

       string returnString = outCoverage;
       if (results.Status != ESRI.ArcGIS.esriSystem.esriJobStatus.esriJobSucceeded)
       {
           returnString = "Changing Failed！";
       }
       return returnString;
   }

当我测试服务时，问题显示为标题.它指向"IWorkSpace"行.
谁可以帮助我呢?谢谢！

When I test the service, the problem shows as the title. It points to the ''IWorkSpace'' line.
Who can help me with it? Thank you!

推荐答案

我自己解决了.
我只是向其中添加代码，如下所示:

I have solved it by myself.
I just add code to it as follows:

public string FeatureClassToCoverage(string string_inFeatures, string string_outCoverage) //List<string string_inFeatures>
{
    <big>ESRI.ArcGIS.esriSystem.IAoInitialize ao = new ESRI.ArcGIS.esriSystem.AoInitialize();
 ao.Initialize(ESRI.ArcGIS.esriSystem.esriLicenseProductCode.esriLicenseProductCodeArcInfo);</big> 

    IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
    IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(System.IO.Path.GetDirectoryName(string_inFeatures), 0);
    IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
    IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(System.IO.Path.GetFileNameWithoutExtension(string_inFeatures));

    String outDict = System.IO.Path.GetDirectoryName(string_inFeatures);
    String outCoverage = outDict + "\\" + string_outCoverage;

    ESRI.ArcGIS.ConversionTools.FeatureclassToCoverage featureClassToCoverage = new FeatureclassToCoverage(pFeatureClass, outCoverage);

    ESRI.ArcGIS.Geoprocessor.Geoprocessor gp = new Geoprocessor();
    ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult results = (ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult)gp.Execute(featureClassToCoverage, null);

    string returnString = outCoverage;
    if (results.Status != ESRI.ArcGIS.esriSystem.esriJobStatus.esriJobSucceeded)
    {
        returnString = "Changing Failed!";
    }
    return returnString;
}

您好，

我不知道string_inFeatures包含什么，但是无论如何，如果它是文件名，那么问题是System.IO.Path.GetDirectoryName(string_inFeatures)返回的是目录名而不是文件路径.

您需要传递文件路径.

有关详细信息，请此处.

Hello,

I don''t know what string_inFeatures contains but anyway if it is a file name then the problem is that System.IO.Path.GetDirectoryName(string_inFeatures) returns a directory name not a file path.

you need to pass a file path.

Look here for details.
