Question

我不确定标题是否恰好描述了我想要实现的目标。简单地说：

如果我有6个输入：

输入1：字符串1

输入2：String1Count

输入3：字符串2

Input4：String2Count

Input5：String3

Input6：String3Count

我想通过字符串各自的计数指定的次数将每个字符串添加到数组。完成此操作后，数组中仍然有空字段，请再次循环这些值并重复该操作，直到数组已满为止。

类似这样的东西

public string str1 = "First String";
public int String1Count = 4;

public string str2 = "Second String";
public int String2Count = 7;

public string str3 = "Third String";
public int String3Count = 5;

int[] arr1 = new int[100];


for (int i = 0; i < arr1.Length; i++)
{
  arr1[i] = str1;
  arr1[i+1] = str1;
  arr1[i+2] = str1;
  arr1[i+3] = str1;
  arr1[i+4] = str1;
  arr1[i+5] = str2;
  arr1[i+6] = str2;
  arr1[i+7] = str2;
  ...
  arr1[arr1.lenght] = str; //It may be str1, str2 or str3, whichever is next
}

我认为至少还需要一个for loop和一些if语句，但我无法弄清楚。

Answer 1

首先，您无法将string分配给int[]数组。您必须将其关联到string[]数组。要解决您的问题，您可以使用模%运算符：

string str1 = "First String";
int String1Count = 4;

string str2 = "Second String";
int String2Count = 7;

string str3 = "Third String";
int String3Count = 5;

string[] arr1 = new string[100];

int sum12 = String1Count + String2Count;
int sum123 = String1Count + String2Count + String3Count;

for (int i = 0; i < arr1.Length; i++)
{
    if (i % sum123 < String1Count)
        arr1[i] = str1;
    else if (i % sum123 < sum12)
        arr1[i] = str2;
    else if (i % sum123 < sum123)
        arr1[i] = str3;
}

可能类似于：

        string str1 = "First String";
        int String1Count = 4;

        string str2 = "Second String";
        int String2Count = 7;

        string str3 = "Third String";
        int String3Count = 5;


        var resultList = new List<String>();
        resultList.AddRange(Enumerable.Repeat(str1, String1Count));
        resultList.AddRange(Enumerable.Repeat(str2, String2Count));
        resultList.AddRange(Enumerable.Repeat(str3, String3Count));

        string[] resultArray = resultList.ToArray();

使用“模板”将值添加到数组
