ArcEngine对COM组件的调用返回了错误 HRESULT E_FAIL

以下为解决办法：（下面两个方法为搜索结果，均未解决我的问题）

1、对 COM 组件的调用返回了错误 HRESULT E_FAIL

(1) 在控制面板--->管理工具--->服务中，开启Distributed Transaction Coordinator 服务。

(2) 打开控制面板--->管理工具--->组件服务--->选择计算机--->我的电脑--->右击属性--->选择MSDTC--->选择安全配置勾选事务管理器通信中的允许出站、允许入站和不要求进行验证。

2、

问题代码：

public static ILayer clip(IFeatureLayer inputfeaturelayer, IFeatureLayer cliplayer)

{

try

{

Geoprocessor gp = new Geoprocessor();

gp.OverwriteOutput = true;

//gp.SetEnvironmentValue("workspace", "Database Connections\\Connection to wsz-nb-pc.sde"); //设置sde路径

//gp.SetEnvironmentValue("outputCoordinateSystem",

// @"C:\Program Files\ArcGIS\Desktop10.0\Coordinate Systems\Projected Coordinate Systems\Gauss Kruger\CGCS 2000\Xian_1980_3_Degree_GK_CM_111E.prj");

IFeatureClass inputfeatureclass = inputfeaturelayer.FeatureClass;

IFeatureClass clipfeatureclass = cliplayer.FeatureClass;

IDataset dataset = inputfeatureclass as IDataset;

IWorkspace workspace = dataset.Workspace;

IFeatureWorkspace fworkspace = workspace as IFeatureWorkspace;

IFields utfields = inputfeatureclass.Fields;

IFeatureClass utfeatureclass = null;

try

{

utfeatureclass = fworkspace.OpenFeatureClass("ClipFile");

if (null != outfeatureclass)

{

//清空记录

IDataset pDataSet = (IDataset)outfeatureclass;

pDataSet.Delete();

}

}

catch (Exception err)

{

utfeatureclass = fworkspace.CreateFeatureClass("ClipFile", outfields, null, null, esriFeatureType.esriFTSimple, "Shape", "");

}

ESRI.ArcGIS.AnalysisTools.Clip clipTool = new ESRI.ArcGIS.AnalysisTools.Clip(inputfeatureclass, clipfeatureclass, outfeatureclass);

gp.Execute(clipTool, null);

IFeatureLayer utlayer = new FeatureLayerClass();

outlayer.FeatureClass = outfeatureclass;

outlayer.Name = outfeatureclass.AliasName;

return outlayer;

}catch(Exception err)

{

MessageBox.Show(string.Format("图层裁剪失败：【{0}】",err.Message), "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Error);

return null;

}

}

该段代码在我的开发环境（xp + AE10 + SDE9.3 + ORACLE10G）中总是提示：

对COM组件的调用返回了错误 HRESULT E_FAIL的错误。

在确定了授权没问题，数据没问题后，将程序改后，成功解决：

public static void clip(IFeatureLayer inputfeaturelayer, IFeatureLayer cliplayer,string strOutShpPath,AxMapControl MapCtr)

{

try

{

Geoprocessor gp = new Geoprocessor();

gp.OverwriteOutput = true;

IFeatureClass inputfeatureclass = inputfeaturelayer.FeatureClass;

IFeatureClass clipfeatureclass = cliplayer.FeatureClass;

ESRI.ArcGIS.AnalysisTools.Clip clipTool = new ESRI.ArcGIS.AnalysisTools.Clip();

clipTool.in_features = inputfeatureclass;

clipTool.clip_features = clipfeatureclass;

clipTool.out_feature_class = strOutShpPath;

GeoProcessorResult gpResult = new GeoProcessorResult();

gpResult = gp.Execute(clipTool, null) as GeoProcessorResult;

string strMsg = "";

for (int i = 0; i < gpResult.MessageCount; i++)

{

strMsg += gpResult.GetMessage(i)+"\n";

}

MessageBox.Show(strMsg);

string shpDir = System.IO.Path.GetDirectoryName(strOutShpPath);

string shpName = System.IO.Path.GetFileNameWithoutExtension(strOutShpPath);

MapCtr.AddShapeFile(shpDir, shpName);//"C:\\temp\\"

}

catch (Exception err)

{

MessageBox.Show(string.Format("图层裁剪失败：【{0}】", err.Message), "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Error);

}

}
