asp.net 获取某个时间段的星期并以表格形式排列出来

string start = Request.Form.Get("date2").ToString(); //获取开始日期，此控件为html控件 
string end = Request.Form.Get("date3").ToString(); //获取结束日期，此控件为html控件 
string[] start_date = start.Split('-'); //分离出开始日期的年、月、日 
string[] end_date = end.Split('-'); //分离出结束日期的年、月、日 
DateTime dt1 = new DateTime(int.Parse(start_date[0]), int.Parse(start_date[1]), int.Parse(start_date[2])); 
DateTime dt2 = new DateTime(int.Parse(end_date[0]), int.Parse(end_date[1]), int.Parse(end_date[2])); 
TimeSpan ts = dt2 - dt1; 
//定义全局变量public string table_td = "";然后进行赋值 
table_td = "<table><tr><td>星期一</td><td>星期二</td><td>星期三</td><td>星期四</td><td>星期五</td><td>星期六</td><td>星期天</td></tr>"; 
//判断开始时间为星期几，如，如果是星期三，则需要前面空出2个单元格出来，以此类推 
switch (dt1.DayOfWeek.ToString()) 
{ 
case "Tuesday": 
table_td += "<tr><td></td>"; 
break; 
case "Wednesday": 
table_td += "<tr><td></td><td></td>"; 
break; 
case "Thursday": 
table_td += "<tr><td></td><td></td><td></td>"; 
break; 
case "Friday": 
table_td += "<tr><td></td><td></td><td></td><td></td>"; 
break; 
case "Saturday": 
table_td += "<tr><td></td><td></td><td></td><td></td><td></td>"; 
break; 
case "Sunday": 
table_td += "<tr><td></td><td></td><td></td><td></td><td></td><td></td>"; 
break; 
} 
//递归至结束时间 
for (int i = 0; i < ts.Days; i++) 
{ 
string sdate = dt1.AddDays(i).Day.ToString(); 
switch (dt1.AddDays(i).DayOfWeek.ToString()) 
{ 
case "Monday": 
table_td += "<tr><td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Tuesday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Wednesday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Thursday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Friday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Saturday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td>"; 
break; 
case "Sunday": 
table_td += "<td><a onmouseover=selStation(1); onmouseout=chide();>" + sdate + "</a></td></tr>"; 
break; 
} 
} 
//结束 
table_td += "</tr></table>"; 
 
打印table_td即可。 
以上是我自己写的，但觉得不怎么样，下面我提供下别人在我做完后，做给我的，代码如下： 
 代码如下:

int weekIndex(string item) 
{ 
string[] week = new string[] { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" }; 
int index = -1; 
for (int i = 0; i < week.Length; i++) 
{ 
if (week[i].Trim().ToUpper() == item.ToUpper().Trim()) 
{ 
index = i; 
break; 
} 
} 
return index; 
} 
 
 代码如下:

StringBuilder sb = new StringBuilder(); 
sb.Remove(0, sb.Length); 
sb.Append("<table><tr><td>星期一</td><td>星期二</td><td>星期三</td><td>星期四</td><td>星期五</td><td>星期六</td><td>星期天</td></tr>"); 
DateTime dt1 = new DateTime(2010, 3, 16); 
DateTime dt2 = new DateTime(2010, 4, 13); 
TimeSpan ts = dt2 - dt1; 
int index; DateTime dtTemp; 
for (int i = 0; i < ts.Days; i++) { 
dtTemp=dt1.AddDays(i); 
index = weekIndex(dtTemp.DayOfWeek.ToString()); 
if (index == 0 && i > 0) 
{ 
sb.AppendFormat("<tr><td>{0}</td>", dtTemp.ToString("MM-dd")); 
} 
else if (index > 0 && i == 0) 
{ 
sb.Append("<tr>"); 
for (int j = 0; j <= index - 1; j++) 
{ 
sb.Append("<td> </td>"); 
} 
sb.AppendFormat("<td>{0}</td>", dtTemp.ToString("MM-dd")); 
} 
else if (index == 6 && i>0) 
{ 
sb.AppendFormat("<td>{0}</td></tr>", dtTemp.ToString("MM-dd")); 
} 
else { 
sb.AppendFormat("<td>{0}</td>", dtTemp.ToString("MM-dd")); 
} 
} 
sb.Append("</table>"); 
Response.Write(sb.ToString()); 
 
看完后，大致上的想法是一样的，只是.......初学者没办法。继续努力。
