在会话计算中将字符串转换为int. [英] convert string to int in session calcu.

问题描述

请检查我在VB.NET中是否有将会话变量转换为美元金额的计算方法.该代码在VB.NET中运行，但在C#中引发错误.我的代码是:

Please check I have a convert session variable into dollar amount calculation in VB.NET. The code is running in VB.NET but in C# it is throwing an error. My code is:

Session("priceday1") = Label2.Text

 Label14.Text = Session("priceday1") / 44

请有人帮助我.当我用C#编写代码时，会引发错误.我在C#中的代码

Please some one help me in this. When I write code in C# it is throwing error. My code in C#

Session["priceday1"] = Label2.Text ;

Label2.Text = Session["priceday1"].ToString() / 44;

推荐答案

尝试一下:)

try this :)

Session["priceday1"] = "5464";
              // Session["priceday1"] = 5464;
           double finalPrice;
           if (Double.TryParse(Session["priceday1"].ToString(), out finalPrice))
           {
               finalPrice = finalPrice / 44;
               Label1.Text = finalPrice.ToString();
           }
           else
           {
               Label1.Text = "Invalid";
           }

这是因为ur将字符串除以44会导致您在字符串中转换会话.

this is Because ur dividing string by 44 as ur converting ur session in string.

Label2.Text = Session["priceday1"].ToString() / 44;

从上面的行中删除.ToString()，然后尝试像

Remove .ToString() from above line and try like

Label2.Text = (Convert.Toint32( Session["priceday1"] )/ 44).ToString();

试试这个

Try this

decimal priceday1 = (decimal) Session["priceday1"] / 44;
Label2.Text = priceday1.ToString("C");
