Self-study "2. Web pop-up calculation of commodity prices

/// <summary>///Goods is a commodity class/// </summary> Public classgoods{ PublicGoods () {//        //TODO: Add constructor logic here//    }     PublicGoods (stringNamedecimalpricedecimal) {         This. Pricedecimal =Pricedecimal;  This. Name =name; }     PublicGoods (stringNamedecimalPricedecimal,stringHtmlurl) {         This. Pricedecimal =Pricedecimal;  This. Name =name; Htmlurl=Htmlurl; }     Public decimalPricedecimal {Get;Set; }  Public stringName {Get;Set; }  Public stringHtmlurl {Get;Set; }}

First write a product class, there is a product name, price, page link address (this example is useless).

usingSystem.Collections.Generic;usingSystem.Text;/// <summary>///Order/// </summary> Public classIndent:list<goods>{     PublicIndent () {//        //TODO: Add constructor logic here//    }    /// <summary>    ///Number of orders/// </summary>     Public intNumber {Get{returnCount;} }    /// <summary>    ///Order Amount/// </summary>     Public decimalGetmoneydecimal () {decimalMoney =0; foreach(Goods Goodsinch  This) { money+=goods.        Pricedecimal; }     returnMoney ; }    /// <summary>    ///Print Order/// </summary>    /// <returns></returns>     Public Override stringToString () {StringBuilder sb=NewStringBuilder (); Sb. Append ("Order Details"); foreach(Goods Goodsinch  This) {sb. Append (goods. Name). Append ("Unit Price:"). Append (goods. Pricedecimal). Append (", "); } sb. Append ("Total:"). Append ( This.        Getmoneydecimal ()); returnsb.    ToString (); }}

Then there is an order class, the order is made up of goods, with list<goods>.

   protected voidButton1_Click (Objectsender, EventArgs e) {Indent myindent=NewIndent (); Goods goods1=NewGoods ("Sickle",2.8m); Goods Goods2=NewGoods ("Axe",5.2m);        Myindent.add (GOODS2);       Myindent.add (GOODS1); stringStr=myindent.tostring (); Response.Write ("<script>alert ('"+ str +"') </script>"); }

The last button test, just fine, haha ^_^

Note: Do this toss me for more than half an hour, is because the last alert, the middle of the string is not a newline character, I used to stringbuilder.appendline (); This method causes the string to have a newline, has been unable to alert out.
