How to add new coded values to an existing domain

RejeanLabbe

I would like to add new coded values to an existing domain, but I don't know how to do that.

I tried to add values like that, but it doesn't work.

oDomainsList = oGeodatabase.GetDomains();
foreach (Domain oDomain in oDomainsList)
{
	if (oDomain != null && oDomain is CodedValueDomain)
	{
		if(oDomain.GetName() == sDomainName)
		{
			(oDomain as CodedValueDomain).GetCodedValuePairs().Add("New value 1", "NV_1");
			break;
		}
	}
}

 

I can create an new domain if it doesn't exists like this :

SortedList<object, string> oList = new SortedList<object, string> {{"Copper", "C_1"}, {"Steel", "S_2"}};

oCodedValueDomainDescription = new CodedValueDomainDescription(sName, FieldType.String, oList)
{
	SplitPolicy = SplitPolicy.Duplicate,
	MergePolicy = MergePolicy.DefaultValue
};

CodedValueDomainToken codedValueDomainToken = schemaBuilder.Create(oCodedValueDomainDescription);
schemaBuilder.Build();

 

But the domain is not overwritten if it exists.

I tried to delete the domain, hopping I could create a new with all coded values, but I don't know how to do that.

SchemaBuilder.Delete needs a Description parameter, but it looks like there is no way to get that from an existing domain.

Remarks
When deleting domains, a CodedValueDomainDescription must be used to delete a ArcGIS.Core.Data.CodedValueDomain and a RangeDomainDescription must be used to delete a ArcGIS.Core.Data.RangeDomain.

There is no example.

Hi, 

You can call the same geoprocessing tools from ArcGIS Pro SDK:

 

                var parameters = Geoprocessing.MakeValueArray(gdb, domName, code, domDict[code]);
                var gpResult = Geoprocessing.ExecuteToolAsync("management.AddCodedValueToDomain", parameters,
                    null, CancelableProgressor.None, GPExecuteToolFlags.None);
