c# Dictionary 遍历，获取key、value

获取value
foreach (Student ss in stu.Values)
{

MessageBox.Show(ss.Name.ToString());
}

***********************************************

获取keyforeach (string key in stu.Keys)

{
MessageBox.Show(key);
}
}
****************

获取key、value
foreach (KeyValuePair<string, Class1> a in cl)
            {
                if (a.Key == s1.Name)
                MessageBox.Show(a.Value.Age.ToString() + "  " + a.Value.Name.ToString ());
            }
****************

连个Dictionary是否相同：

foreach (var kvp in DictionaryA)
{    
int value;    
if (DictionaryB.TryGetValue(kvp.Key, out value))   
 {       
 if (kvp.Value != value)   
     {        
    hasDictionaryChanged = true;         
   break;    
    }  
  }}
****************

using System.Linq;

Dictionary<int, string> students;

  var values = from u in students    
           let temp = u.Value.Scores.Sum()  orderby temp
              select new {
name = u.Value.Name, totalscore = temp
};
   ///显示查询结果
var dicSort = from d in letterWordTotalNum                                  
orderby d.Key
select d;

***********************************************

转换为数组：

Dictionary<uint, object> dic = new Dictionary<uint, object>();

object[] r = (from val in dic select val.Value).ToArray<object>();
