将数据结构传递给函数并访问数据结构的字段，如C＃中的数组 [英] Pass a data structure to a function and access the fields of the data structure like an array in C#

问题描述

我有一组不同类型的字段，我必须将它们分组成任何数据结构。然后我必须将其传递给一个函数，并用数组修改数据结构的索引。
我该怎么做？感谢大家。

  mytype {
 int a; 
 ushort b; 
 string c; 
} 
  

我想传递这些数据结构，将所有这些字段组合起来可以是类或结构体。并将其传递给一个函数，并希望使用索引修改该实例的字段，如下所示：

  void function mytype G）
 {
 G [1] = 1; < =这里Ga应设置为1 
} 
  

解决方案

您可以使用对象列表：

  var list = new List< object>（）; 
 list.Add（strings are cool！）; 
 list.Add（42）; 
 
 // ... 
 
 var objByIndex = list [1]; // 42 
  

尽管如此，如果您这样做，您将失去C＃强力打字的所有优点。我建议使用具有明确定义的强类型属性的类，除非你真的需要一些通用的东西（在这里你不知道属性的类型）。

I have a set of fields of different types, I must group them into any data structure. Then I have to pass it to a function and modify the fields the data structure with indexes, like array. How would I do this? Thanks to everyone.

mytype{
   int a;
   ushort b;
   string c;
}

And I would like to pass this data structure that groups all these fields, it can be class or struct. And Pass this to a function and would like to modify the fields of that instance with indexes, like this:

void function(ref mytype G)
{
    G[1] = 1;   <= Here G.a should be set to 1
}

解决方案

You could use a list of objects:

var list = new List<object>();
list.Add("strings are cool!");
list.Add(42);

// ...

var objByIndex = list[1];        // 42

You lose all the advantages of C#'s strong-typing if you do this, though. I would suggest using a class with well-defined, strongly typed properties instead, unless you really need something generic (where you don't know anything about the properties' types before-hand).
