    Creating a Table
    public void CreateTableSnippet(Geodatabase geodatabase, CodedValueDomain inspectionResultsDomain)
    {
      // Create a PoleInspection table with the following fields
      //  GlobalID
      //  ObjectID
      //  InspectionDate (date)
      //  InspectionResults (pre-existing InspectionResults coded value domain)
      //  InspectionNotes (string)
    
      // This static helper routine creates a FieldDescription for a GlobalID field with default values
      FieldDescription globalIDFieldDescription = FieldDescription.CreateGlobalIDField();
    
      // This static helper routine creates a FieldDescription for an ObjectID field with default values
      FieldDescription objectIDFieldDescription = FieldDescription.CreateObjectIDField();
    
      // Create a FieldDescription for the InspectionDate field
      FieldDescription inspectionDateFieldDescription = new FieldDescription("InspectionDate", FieldType.Date)
      {
        AliasName = "Inspection Date"
      };
    
      // This static helper routine creates a FieldDescription for a Domain field (from a pre-existing domain)
      FieldDescription inspectionResultsFieldDescription = FieldDescription.CreateDomainField("InspectionResults", new CodedValueDomainDescription(inspectionResultsDomain));
      inspectionResultsFieldDescription.AliasName = "Inspection Results";
    
      // This static helper routine creates a FieldDescription for a string field
      FieldDescription inspectionNotesFieldDescription = FieldDescription.CreateStringField("InspectionNotes", 512);
      inspectionNotesFieldDescription.AliasName = "Inspection Notes";
    
      // Assemble a list of all of our field descriptions
      List<FieldDescription> fieldDescriptions = new List<FieldDescription>()
        { globalIDFieldDescription, objectIDFieldDescription, inspectionDateFieldDescription, inspectionResultsFieldDescription, inspectionNotesFieldDescription };
    
      // Create a TableDescription object to describe the table to create
      TableDescription tableDescription = new TableDescription("PoleInspection", fieldDescriptions);
    
      // Create a SchemaBuilder object
      SchemaBuilder schemaBuilder = new SchemaBuilder(geodatabase);
    
      // Add the creation of PoleInspection to our list of DDL tasks
      schemaBuilder.Create(tableDescription);
    
      // Execute the DDL
      bool success = schemaBuilder.Build();
    
      // Inspect error messages
      if (!success)
      {
        IReadOnlyList<string> errorMessages = schemaBuilder.ErrorMessages;
        //etc.
      }
