我希望用C#来做这件事。
public struct Structure1
{ string string1 ; //Can be set dynamically
public string[] stringArr; //Needs to be set dynamically
}
一般情况下,如果需要,应如何动态初始化数组? 简单来说,我试图在C#中实现这一点:
int[] array;
for (int i=0; i < 10; i++)
array[i] = i;
另一个例子:
string[] array1;
for (int i=0; i < DynamicValue; i++)
array1[i] = "SomeValue";

首先,您的代码几乎可以正常工作:
int[] array = new int[10]; // This is the only line that needs changing
for (int i=0; i < 10; i++)
array[i] = i;
您可以通过添加自定义构造函数来初始化结构中的数组,然后在创建结构时调用构造函数初始化它。这是课程所必需的。
话虽这么说,我强烈建议在这里使用一个类而不是结构。可变结构是一个坏主意 - 包含引用类型的结构也是一个非常糟糕的主意。
编辑:
如果您尝试制作长度为动态的集合,则可以使用List<T>
而不是数组:
List<int> list = new List<int>();
for (int i=0; i < 10; i++)
list.Add(i);
// To show usage...
Console.WriteLine("List has {0} elements. 4th == {1}", list.Count, list[3]);

int[] arr = Enumerable.Range(0, 10).ToArray();

int x=10;
int[] arr = Enumerable.Range(0, x).ToArray();

// IF you are going to use a struct
public struct Structure1
{
readonly string String1;
readonly string[] stringArr;
readonly List<string> myList;
public Structure1(string String1)
{
// all fields must be initialized or assigned in the
// constructor
// readonly members can only be initialized or assigned
// in the constructor
this.String1 = String1
// initialize stringArr - this will also make the array
// a fixed length array as it cannot be changed; however
// the contents of each element can be changed
stringArr = new string[] {};
// if you use a List<string> instead of array, you can
// initialize myList and add items to it via a public setter
myList = new List<string>();
}
public List<string> StructList
{
// you can alter the contents and size of the list
get { return myList;}
}
}
