Question

鉴于下面的类，将多个字符串添加到名为blob_key_col_name的StringCollection中的正确方法是什么？

public class blob_info
{
    public string column_name { get; set; }
    public string blob_value { get; set; }
    public int column_pos { get; set; }
    public string blob_key { get; set; }
    public int blob_key_count { get; set; }
    public StringCollection blob_key_col_name { get; set; }


    public blob_info(string column_name, string blob_value, int column_pos, string blob_key, int blob_key_count)
    {
        this.column_name = column_name;
        this.blob_value = blob_value;
        this.column_pos = column_pos;
        this.blob_key = blob_key;
        this.blob_key_count = blob_key_count;
        blob_key_col_name = new StringCollection();
    }
}

public static List<blob_info> blob_col = new List<blob_info>();

void main
{
   blob_col.Add(new blob_info("Column_name","pathname",0,"key_column_name",0,blob_key_col_name.Add("")));
}

那将是使用：

from operator import itemgetter
a = [[1, 3, 5], [2, 511, 7], [17, 233, 1]]
a = sorted(a, key=itemgetter(1))
