c# - 我如何遍历 OracleDataReader 的所有列

Question

我有以下代码，我想遍历此查询结果中的所有字段并填充名为字段的字典。

给定数据读取器这可能吗？

            OracleCommand command = connection.CreateCommand();
            string sql = "Select * from MYTABLE where ID = " + id;
            command.CommandText = sql;

            Dictionary<string, string> fields = new Dictionary<string, string>();
            OracleDataReader reader = command.ExecuteReader();

Answer 1

你应该能够做这样的事情:

Dictionary<string, string> fields = new Dictionary<string, string>();
OracleDataReader reader = command.ExecuteReader();

if( reader.HasRows )
{
    for( int index = 0; index < reader.FieldCount; index ++ )
    {
        fields[ reader.GetName( index ) ] = reader.GetString( index );
    }    
}
