Dictionary<string,int> NewLengths = new Dictionary<string,int>();
for (int n = 0; n < tableArray.Length - 1; n++)
{
for (int u = 0; u < TableLengths.Count; u++)
{
if (TableLengths[u].Name == tableArray[n])
{
NewLengths.Add(TableLengths[u].Name,TableLengths[u].Length);
}
}
}NewLengths的值为:
"aaa",3
"ddd",4
"fff",2
"rrr",1我现在要将这个数据字典按照value值排序,即为
"rrr",1
"fff",2
"aaa",3
"ddd",4
最后的保存形式可以为数据字典,不行的话为List也行啊,求怎么排序呢
string[] itemList =new string[] { "x=10", "y=5", "k=4", "r=9" };
int flag = 1; int i, j; int itemCount = itemList.Length; string itemTemp; for (i = 1; i < itemCount && flag == 1; i++)
{
flag = 0; for (j = 0; j < itemCount - i; j++)
{
string itemfore = itemList[j]; int countfore = Convert.ToInt32(itemfore.Substring(itemfore.IndexOf('=') + 1, itemfore.Length - (itemfore.IndexOf('=') + 1))); string itemback = itemList[j + 1]; int countback = Convert.ToInt32(itemback.Substring(itemback.IndexOf('=') + 1, itemback.Length - (itemback.IndexOf('=') + 1))); if (countfore < countback)
{
flag = 1; itemTemp = itemList[j]; itemList[j] = itemList[j + 1]; itemList[j + 1] = itemTemp;
}
}
}
return itemList;
}这是我曾经用到的一个排序。
{
static int keySelector(KeyValuePair<string, int> entry)
{
return entry.Value;
} static void Main()
{
Dictionary<string, int> vals = new Dictionary<string, int>();
vals.Add("asp.net", 3);
vals.Add("vb.net", 2);
vals.Add("html5", 1); IOrderedEnumerable<KeyValuePair<string, int>> result = vals.OrderBy(keySelector); foreach (var item in result)
Console.WriteLine("{0}:{1}", item.Key, item.Value); }
}
