构造函数
| DbSpatialDataReader() |
初始化 DbSpatialDataReader 类的新实例。Initializes a new instance of the DbSpatialDataReader class. |
方法
| Equals(Object) |
确定指定对象是否等于当前对象。Determines whether the specified object is equal to the current object. (继承自 Object) |
| GetGeography(Int32) |
当在派生类型中实现时,从指定列序号的列读取 DbGeography 的实例。When implemented in derived types, reads an instance of DbGeography from the column at the specified column ordinal. |
| GetGeometry(Int32) |
当在派生类型中实现时,从指定列序号的列读取 DbGeometry 的实例。When implemented in derived types, reads an instance of DbGeometry from the column at the specified column ordinal. |
| GetHashCode() |
作为默认哈希函数。Serves as the default hash function. (继承自 Object) |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| MemberwiseClone() |
创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object) |
| ToString() |
返回表示当前对象的字符串。Returns a string that represents the current object. (继承自 Object) |
