IDesignerDataSchema.SupportsSchemaClass(DesignerDataSchemaClass) 方法
定义
返回一个值,该值指示数据存储区是否包含指定的数据架构对象。Returns a value indicating whether the data store contains the specified data-schema object.
public:
bool SupportsSchemaClass(System::ComponentModel::Design::Data::DesignerDataSchemaClass ^ schemaClass);
public bool SupportsSchemaClass (System.ComponentModel.Design.Data.DesignerDataSchemaClass schemaClass);
abstract member SupportsSchemaClass : System.ComponentModel.Design.Data.DesignerDataSchemaClass -> bool
Public Function SupportsSchemaClass (schemaClass As DesignerDataSchemaClass) As Boolean
参数
- schemaClass
- DesignerDataSchemaClass
要返回的架构对象。The schema objects to return.
返回
如果数据存储区支持指定的数据架构对象,则为 true;否则为 false。true if the data store supports the specified data-schema object; otherwise, false.
注解
SupportsSchemaClass方法指示数据存储区是否支持指定的数据架构对象。The SupportsSchemaClass method indicates whether the data store supports a specified data-schema object. 如果数据存储不支持指定的对象,则该 SupportsSchemaClass 方法应返回 false 。If the data store does not support the specified object, the SupportsSchemaClass method should return false.
您可以通过从类派生,为其他数据架构对象添加测试 DesignerDataSchemaClass 。You can add tests for additional data-schema objects by deriving from the DesignerDataSchemaClass class.
