程序简要代码如下：
esriGeoDatabase::IFeatureWorkspacePtr spFeaWs = spWorkspace;
esriGeoDatabase::IWorkspaceEditPtr spWsEdit = spFeaWs;
spWsEdit-> StartEditing(VARIANT_TRUE);
spWsEdit-> StartEditOperation();
esriGeoDatabase::IFeatureClassPtr spFeatureClass;
spFeaWs-> raw_OpenFeatureClass(sDestTbName.AllocSysString(),&spFeatureClass);
esriGeoDatabase::IFeatureBufferPtr spFeatureBuf;
esriGeoDatabase::IFeatureCursorPtr spFeacureCursor;
spFeacureCursor = spFeatureClass-> Insert(VARIANT_TRUE);
if (spFeacureCursor == NULL)
{
return FALSE;
}
执行insert时，总是出现错误 “无效的参数量”
请高手给予回答啊，急啊
------解决方案--------------------
帮助中有这么一个例子，你可以看一下
[C#]
public void IFeatureClass__Insert(IFeatureClass featureClass)
{
//get the Workspace from the IDataset interface on the feature class
IDataset dataset = (IDataset)featureClass;
IWorkspace workspace = dataset.Workspace;
//Cast for an IWorkspaceEdit
IWorkspaceEdit workspaceEdit = (IWorkspaceEdit)workspace;
//Start an edit session and operation
workspaceEdit.StartEditing(true);
workspaceEdit.StartEditOperation();
//Create the Feature Buffer
IFeatureBuffer featureBuffer = featureClass.CreateFeatureBuffer();
//Create insert Feature Cursor using buffering = true.
IFeatureCursor featureCursor = featureClass.Insert(true);
object featureOID;
//With a feature buffer you have the ability to set the attribute for a specific field to be
//the same for all features added to the buffer.
featureBuffer.set_Value(featureBuffer.Fields.FindField( "InstalledBy "), "K Johnston ");
//Here you can set the featurebuffers 's shape by setting the featureBuffer.Shape
//to a geomerty that matched the featureclasses.
//Insert the feature into the feature cursor
featureOID = featureCursor.InsertFeature(featureBuffer);
//Calling flush allows you to handle any errors at a known time rather then on the cursor destruction.
featureCursor.Flush();
//Stop editing
workspaceEdit.StopEditOperation();
workspaceEdit.StopEditing(true);
//Release the Cursor
System.Runtime.InteropServices.Marshal.ReleaseComObject(featureCursor);
}
