Get Entity Logical Name from its Object Type Code in Dynamics 365

Being a CRM developer, while writing the code, you might need to get the Entity Logical Name from its Object Type Code,

So here is the code to do the same:

public static string geEntityLogicalName(int ObjectTypeCode)
{

            string entityLogicalName = String.Empty;

            MetadataFilterExpression EntityFilter = 

new MetadataFilterExpression(LogicalOperator.And);

            EntityFilter.Conditions.Add(new MetadataConditionExpression

("ObjectTypeCode", MetadataConditionOperator.Equals, ObjectTypeCode));

            MetadataPropertiesExpression mpe = new MetadataPropertiesExpression();

            mpe.AllProperties = false;

            mpe.PropertyNames.Add("ObjectTypeCode");

            EntityQueryExpression entityQueryExpression = new EntityQueryExpression()
            {

                Criteria = EntityFilter,

                Properties = mpe

            };


            RetrieveMetadataChangesResponse initialRequest = 

GetMetadataChanges(entityQueryExpression, null, DeletedMetadataFilters.OptionSet);

            if (initialRequest.EntityMetadata.Count == 1)
            {

                entityLogicalName = initialRequest.EntityMetadata[0].LogicalName;

            }

            return entityLogicalName;

        }


        protected static RetrieveMetadataChangesResponse GetMetadataChanges

(EntityQueryExpression entityQueryExpression, String clientVersionStamp, DeletedMetadataFilters deletedMetadataFilter)
        {

            RetrieveMetadataChangesRequest retrieveMetadataChangesRequest = 

new RetrieveMetadataChangesRequest();
            {

                Query = entityQueryExpression,

                ClientVersionStamp = clientVersionStamp,

                DeletedMetadataFilters = deletedMetadataFilter

            };


            return (RetrieveMetadataChangesResponse)service.Execute(retrieveMetadataChangesRequest);

  }
