Example
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.
  }
}
