dropdownlist中的字符串在itextshpar中包含<

Question

My application is MVC5, I get a string value from a dropdownlist, the item value is <20%.

If I try to append another string with the value of the item it cuts it.

for example:

string itemvalue = x; /*item value from the dropdownlist*/
string totalvalue = "score" + x;

on debug, the total value = score <20%. However when I print it using itextsharp HTMLWorker I only get score!

Answer 1

the < is an html tag. you can replace it with <

string itemvalue = x; /*item value from the dropdownlist*/
string totalvalue = "score" + x;
totalvalue.Replace("<","&lt;");
// you can use it now! ;)

Answer 2

I think using this will solve your issue

string itemvalue = x; /*item value from the dropdownlist*/
string totalvalue = String.Format( "score{0}",x);

Why not this remove % from String

 String.Format( "score{0}%",x);

OR

 String.Format( "score{0:00%}",x);

Answer 3

我使用HttpUtility.HtmlEncode（totalvalue），有效。
