IFieldsEdit.AddField() throws HRESULT: 0x80040705

SebastianKrings — Sun, 12 Dec 2021 16:51:49 GMT

Hello,

I want to create a feature Class within a Geodatabase (the code below).
When computing

IFieldsEdit.AddField(IFieldEdit)

it crashes and returns

"Exception from HRESULT: 0x80040705"

It wouold be grateful if somebody could get any help or ideas to solve this problem.
Thanks!

Here are some object-values at runtime:

IFieldsEdit:

base {System.__ComObject} System.MarshalByRefObject {System.__ComObject}

Identity null object

and this is the code i want to run:

public IFeatureClass CreateFeatureClassInWorkspace(String featureClassName, IFeatureWorkspace featureWorkspace)

            try

                // Instantiate a feature class description to get the required fields.

                IFieldsEdit fieldsEdit = (IFieldsEdit)fields;

                // Add an object ID field to the fields collection. This is mandatory for feature classes.
                IField oidField = new FieldClass();
                IFieldEdit oidFieldEdit = (IFieldEdit)oidField;
                oidFieldEdit.Name_2 = "OID";
                oidFieldEdit.Type_2 = esriFieldType.esriFieldTypeOID;
                fieldsEdit.AddField(oidFieldEdit);

                // Create a geometry definition (and spatial reference) for the feature class.
                IGeometryDef geometryDef = new GeometryDefClass();
                IGeometryDefEdit geometryDefEdit = (IGeometryDefEdit)geometryDef;
                geometryDefEdit.GeometryType_2 = esriGeometryType.esriGeometryPoint;

                spatialReferenceTolerance.SetDefaultXYTolerance();
                geometryDefEdit.SpatialReference_2 = spatialReference;

                // Add a geometry field to the fields collection. This is where the geometry definition is applied.
                IField geometryField = new FieldClass();
                IFieldEdit geometryFieldEdit = (IFieldEdit)geometryField;
                geometryFieldEdit.Name_2 = "Shape";
                geometryFieldEdit.Type_2 = esriFieldType.esriFieldTypeGeometry;
                geometryFieldEdit.GeometryDef_2 = geometryDef;
                fieldsEdit.AddField(geometryField);

                // Add a Name text field to the required fields.
                IField field = new FieldClass();
                IFieldEdit fieldEdit = (IFieldEdit)field;
                fieldEdit.Name_2 = "Name";
                fieldEdit.Type_2 = esriFieldType.esriFieldTypeString;
                fieldsEdit.AddField(field);

                // Use IFieldChecker to create a validated fields collection.
                IFieldChecker fieldChecker = new FieldCheckerClass();
                IEnumFieldError enumFieldError = null;
                IFields validatedFields = null;
                fieldChecker.ValidateWorkspace = (IWorkspace)featureWorkspace;
                fieldChecker.Validate(fields, out enumFieldError, out validatedFields);

                // The enumFieldError enumerator can be inspected at this point to determine 
                // which fields were modified during validation.

                // Create the feature class.
                IFeatureClass featureClass = featureWorkspace.CreateFeatureClass
                  (featureClassName, validatedFields, ocDescription.InstanceCLSID,
                  ocDescription.ClassExtensionCLSID, esriFeatureType.esriFTSimple,
                  fcDescription.ShapeFieldName, "");
                return featureClass;
            }
            catch (Exception e)
            {
                Console.WriteLine(e.StackTrace);
                throw e;
            }

In .NET you need to append "_2" to the property you want to set on this interface. This is mentioned in the IFieldsEdit documentation.

It looks like you're adding the required fields with this line:

IFields fields = ocDescription.RequiredFields;

The OID is a required field so I imagine you're getting the error because you're trying to add it a second time with this code.

// Add an object ID field to the fields collection. This is mandatory for feature classes.
                IField oidField = new FieldClass();
                IFieldEdit oidFieldEdit = (IFieldEdit)oidField;
                oidFieldEdit.Name_2 = "OID";
                oidFieldEdit.Type_2 = esriFieldType.esriFieldTypeOID;
                fieldsEdit.AddField(oidFieldEdit);

Hi
thanks a lot.

Do you know which Fields are all Required Field?
I would expect that OID ans Shape are the required fields.
Or are there some more Fields?

Refer to the developer help topic for IObjectClassDescription.RequiredFields. You can also loop through the Fields object it returns and see what fields it put in there.
