根据方括号中的项数将字符串拆分为多个字符串C#

string[] result = inputString.Split(separator);

string input = "根据方括号中的项数将字符串拆分为多个字符串";
int itemCount = 5; // 方括号中的项数

// 计算每个子字符串的长度
int substringLength = input.Length / itemCount;

// 拆分字符串
string[] substrings = new string[itemCount];
for (int i = 0; i < itemCount; i++)
{
    int startIndex = i * substringLength;
    int length = (i == itemCount - 1) ? input.Length - startIndex : substringLength;
    substrings[i] = input.Substring(startIndex, length);
}

// 输出拆分后的子字符串
foreach (string substring in substrings)
{
    Console.WriteLine(substring);
}
