abstract member CreateRowUpdatingEvent : System.Data.DataRow * System.Data.IDbCommand * System.Data.StatementType * System.Data.Common.DataTableMapping -> System.Data.Common.RowUpdatingEventArgs
Protected Overridable Function CreateRowUpdatingEvent (dataRow As DataRow, command As IDbCommand, statementType As StatementType, tableMapping As DataTableMapping) As RowUpdatingEventArgs
Protected MustOverride Function CreateRowUpdatingEvent (dataRow As DataRow, command As IDbCommand, statementType As StatementType, tableMapping As DataTableMapping) As RowUpdatingEventArgs
参数
- command
- IDbCommand
要在 IDbCommand 过程中执行的 Update(DataSet)。
- statementType
