如何在C#中求解方程 [英] How to solve equations in c#

问题描述

嗨
我想在asp.net c#中求解一个方程式

等式是

Hi
I want to solve an equation in asp.net c#

Equation is

int x0 = 5;
     int x1 = 2;

然后

then

y = (x-x0)/(x0-x1)

它应该像
一样返回

it should return like

y = (x-5)/3;

但是

它显示了x不确定的错误....


请帮我解决这个问题.


致以问候

在此先感谢

Manju K

But

It shows an error like x is undefined....


Please help me in solving this.


With Regards

Thanks in Advance

我看不到您已经声明了变量x，y
这样编译器就会抛出该错误

要解决该错误，您可以在函数中声明x，y变量，例如:

i don''t see you have been declare variable x, y
so that the compiler throws that error

to solve that error, you can declare x, y variable inside your function like:

int x = 100; // value 100 is an example 
int y = 100; // value 100 is an example 
int x0 = 5;
int x1 = 2;

....

或编写如下函数:

....

or write an function like:

public int MyEquation(int x)
{
     int y;

     // here is your code

     return y;
}

您需要在这里告诉我们您要实现的目标.使用给定的信息，可以很容易地通过String.Format完成此操作.但这对您有帮助吗?我认为不会.

You need to tell us what exactly you are trying to acheieve here. With the given information, this can be very easily done through String.Format. But does it help you? I think it will not.

int x0 = 5;
int x1 = 3;
string originalString = "y = (x-{0})/({1})";

string updatedString = string.Format(originalString, x0, (x0 - x1));

您需要实现自己的解析器，以解决方程式.需要充分了解您的要求以帮助您.在Google中搜索"C#Equation Parser".它可能会给您一些思路.

You need to implement a parser of your own which could solve the equations. One needs to be well aware of your requirements to help you out. Search google for "C# Equation Parser". It may give you some ideas to start with.
