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;
   }

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!

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;
}

Solution 3

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.

I am sure that my file path is right, and my problem is solved by myself.
Thank you very much, anyway:)
Maybe we can communicate more about programming, do you have a MSN or else?
