价值在Zero之前

问题描述

这里在下面的代码EstbFee = 0.00和FutureEstbFee = 4000.10但是当我试图添加这两个时它导致04000.1而不是它的总和应该显示4000.10。如何解决它

here in the below code EstbFee=0.00 and FutureEstbFee=4000.10 but when im trying to add these two it's resulting in "04000.1" rather it’s sum should display 4000.10 . How can solve it

txtEstablishmentFee.Text = (Convert.ToDouble(dt.Rows[0]["EstablishmentFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstablishmentFee"])).ToString().Trim();

提前致谢

Thanks in advance

推荐答案

txtEstbFee.Text = (Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"])).ToString().Trim();

或者更好地分成几个步骤：

Or better break into several steps:

var estbFee = Convert.ToDouble(dt.Rows[0]["EstbFee"]);
var futureEstbFee = Convert.ToDouble(dt.Rows[0]["FutureEstbFee"]);
var totalFee = estbFee + futureEstbFee; 
txtEstbFee.Text = totalFee.ToString();

这种方式很容易阅读。

This way it's easy to read.

txtEstbFee.Text = (Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"])).ToString();

或者更好：

Or better:

txtEstbFee.Text = ((double)dt.Rows[0]["EstbFee"] + (double)dt.Rows[0]["FutureEstbFee"]).ToString();

假设您的列是数字的。如果它们不是，它们应该是！

Assuming your columns are numeric. If they aren't, they should be!

double value = Convert.ToDouble(dt.Rows[0]["EstbFee"]) + Convert.ToDouble(dt.Rows[0]["FutureEstbFee"]);
txtEstbFee.Text = value.ToString().Trim();

祝你好运！



ps。为什么列字符串而不是小数类型？然后不需要转换。

Good luck!

ps. why are the columns string instead of beeing a decimal type? Then no conversion is needed.
