Question

无法将类型“System.Data.OleDb.OleDbDataReader”隐式转换为“System.Data.OleDb.OleDbDataAdapter"

求救啊！~~
用c#连接access（winform中）
OleDbDataAdapter dr = DBOperate.ExecuteReader(strsql);//就是这句报错了
DBOperate是一个accesshelper操作类

___________________________如下是DBOperate中的ExecuteReader方法
public static OleDbDataReader ExecuteReader(string strSQL)
{
OleDbConnection connection = new OleDbConnection(connectionString);
OleDbCommand cmd = new OleDbCommand(strSQL, connection);
try
{
connection.Open();
OleDbDataReader myReader = cmd.ExecuteReader();
return myReader;
}
catch (System.Data.OleDb.OleDbException e)
{
throw new Exception(e.Message);
}

}

刚刚编译就报错了。。。。
