C# 在ASP.NET中运行的应用程序未提供所需的输出

我有一个应用程序没有正确计算百分比。假设以百分比计算输入。但在某个地方有一个bug阻止它这么做

例如，如果我输入任何以小数开头的数字，如

0.01

或

0.001

或

0.02

等，它将分别给出输出

1

、

0.1

和

2

。如果我输入任何整数，如

1

、

2

、

3

、

10

，它将始终给出相同的输出，即

0.01

这项申请是由一些承包商在5年前提出的。负责此应用程序的主管已离开。这让我和我在c#和asp.net方面的一点经验都无法解决这个问题。在我寻求任何进一步的帮助之前，我想我应该问问那里的天才们，看看他们有什么要说的，也许在你们的帮助下，我最终会解决这个问题。我确实和我部门的其他IT人员谈过，他们猜测可能是因为下面的代码

    if (int.TryParse(string.IsNullOrEmpty(txtminup.Text) ? "0" : txtminup.Text, out n))

我不是100%确定如何调试或找到问题。如果有人能给我指出任何可能对我有帮助的东西，或者提供一些我可以查阅的资源，那将非常有帮助。我复制了几行代码。我可以提供更多信息，但不知道哪一个更相关

@Umaheswaran谢谢你的提示

    int n;
    if (int.TryParse(string.IsNullOrEmpty(txtminup.Text) ? "0" : txtminup.Text, out n))

上面是初始代码，我将其更改为

     double n;
    if (double.TryParse(string.IsNullOrEmpty(txtminup.Text) ? "0" : txtminup.Text, out n))

    Convert.ToDouble 

无论它在什么地方转变为

   Convert.ToInt32

我把它改成了

     double n;
    if (double.TryParse(string.IsNullOrEmpty(txtminup.Text) ? "0" : txtminup.Text, out n))

    Convert.ToDouble 

我不知道是什么问题，因为我对asp.net和c不太熟悉，但更改上述代码解决了问题。现在，每当我输入一个数字，它都会变为百分比，并将其保存为正确的格式

---

谢谢大家的帮助和关心。我还有一些不同的问题。我会尽力解决它，如果不是，我会把它贴在这里，尽量简洁和中肯

问题是什么？你想让我们做什么？请解释更多这是代码中唯一进行计算的部分吗？将代码的其余部分张贴在它们相乘的地方，这也有助于看到更高的层次。您能否给我们代码的其余部分，因为这甚至不是一个公平的示例，因为

n

是从未使用过的解析值@A.Pasa如果您在此处列出的代码必须将整个num转换为十进制，则应使用类似以下的convert.ToString（（float）convert.ToInt32（MinUp）/100）而不是convert.ToString（convert.ToInt32（MinUp）/100）
