ExecuteReader(IRelationalConnection, IReadOnlyDictionary<String,Object>)
使用 RelationalDataReader 结果执行命令。
public Microsoft.EntityFrameworkCore.Storage.RelationalDataReader ExecuteReader (Microsoft.EntityFrameworkCore.Storage.IRelationalConnection connection, System.Collections.Generic.IReadOnlyDictionary<string,object> parameterValues);abstract member ExecuteReader : Microsoft.EntityFrameworkCore.Storage.IRelationalConnection * System.Collections.Generic.IReadOnlyDictionary<string, obj> -> Microsoft.EntityFrameworkCore.Storage.RelationalDataReaderPublic Function ExecuteReader (connection As IRelationalConnection, parameterValues As IReadOnlyDictionary(Of String, Object)) As RelationalDataReader参数
- connection
- IRelationalConnection
要对其执行的连接。
- parameterValues
- IReadOnlyDictionary<String,Object>
参数的值。
返回
命令的结果。
适用于
ExecuteReader(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean)
注意
Use overload without 'manageConnection' parameter
使用 RelationalDataReader 结果执行命令。
