C＃通过索引引用数组元素不起作用 [英] C# referencing array element by index not working

问题描述

请帮助在C＃中按索引访问数组元素。我有一系列我们提供的服务，我想点击某个按钮来累积每种服务的总数。我已经声明了一系列服务总计和一个累积总计的简单方法

这是我的代码的骨架：

Please help with accessing array element by index in C#. I have an array of services we offer and I want at the click of a button somewhere to accumulate totals per type of service. I have declared an array of service totals and a simple method to accumulate totals
Here is the skeleton of my code:

private int[] serviceTotals = new int[10];  

 public void AccumulateTotals()
 int indexInteger=0;
 int serviceCount +=1;
 ServiceTotals[indexInteger]+=serviceCount;

问题是程序中的其他地方我称之为方法&使用此代码：

The problem is somewhere else in the program I call the the method & use this code:

AccummulateTotals()

Textbox1.Text = serviceTotals[0].ToString //for the first item in the array

我收到一个错误：无法将带有[]的索引应用于'int'类型的表达式

我做错了什么？



：调整后的代码标签

I get an error: "Cannot apply indexing with[] to an expression of type 'int'
What am I doing wrong??

: Adjusted code-tags

推荐答案

C＃区分大小写。 ServiceTotals 与 serviceTotals 不同。

C# is case sensitive. ServiceTotals is not the same as serviceTotals.

试试这个：

Try this :

public int[] serviceTotals = new int[10];

填充数组：

to fill the array :

int serviceCount =1;
         for (int i = 0; i < serviceTotals.Count(); i++)
         {
             serviceTotals[i] = serviceCount;
             serviceCount++;
         }

拨打第一项：

to call the first item :

MessageBox.Show(serviceTotals[0].ToString());

它必须有效，除非你指向不同类型的不同变量！区分大小写可能是问题。

it must work unless you're pointing to a different variable with different type! Case sensitivity may be the issue.
