1、string.Split

   string
    str 
   =
    
   "
   abc$$123$4$5
   "
   ;

   string
   [] strs 
   =
    str.Split(
   new
    
   string
   [] { 
   "
   $$
   "
    }, StringSplitOptions.RemoveEmptyEntries);

   foreach
    (
   string
    s 
   in
    strs)

   {

     Response.Write(s 
   +
    
   "
   <hr />
   "
   );

   }
  

 2、查看指定端口号连接情况

netstat -abn | find "8800" 

3、SortedList

   
            SortedList
    <
    int
    , 
    int
    >
     list 
    =
     
    new
     SortedList
    <
    int
    , 
    int
    >
    (
    100
    );
        
    for
     (
    int
     i 
    =
     
    0
    ; i 
    <
     
    100
    ; i
    ++
    )
        {
            list.Add(i, i 
    +
     
    1000
    );
        }
        list.TrimExcess();

        
    for
     (
    int
     i 
    =
     
    80
    ; i 
    <
     
    120
    ; i
    ++
    )
        {
            Response.Write(
    string
    .Format(
    "
    InternalID={0}, IndexOfKey={1} <br/>
    "
    , i, list.IndexOfKey(i)));
            
    int
     userid 
    =
     
    0
    ;
            list.TryGetValue(i, 
    out
     userid);
    //
    userid不存在会返回0
    

                Response.Write(
    string
    .Format(
    "
    InternalID={0}, UserId={1} <br/>
    "
    , i, userid));
            Response.Write(
    "
    <hr />
    "
    );
        }
   
  

 

   
            SortedList
    <
    int
    , 
    int
    >
     list 
    =
     
    new
     SortedList
    <
    int
    , 
    int
    >
    (
    100
    );
        
    for
     (
    int
     i 
    =
     
    0
    ; i 
    <
     
    100
    ; i
    ++
    )
        {
            
    //
    由小到大排序
    

                list.Add(Guid.NewGuid().ToString().GetHashCode(), i);
        }
        list.TrimExcess();

        
    foreach
     (KeyValuePair
    <
    int
    , 
    int
    >
     kv 
    in
     list)
        {
            Response.Write(
    string
    .Format(
    "
    {0}, {1}
    "
    , kv.Key, kv .Value));
            Response.Write(
    "
    <hr />
    "
    );
        }
