public static int getAge(int yearOfBirth) 
{
    int CurrentYear = DateTime.Now.Year;
    int age = CurrentYear - yearOfBirth;
    return age;
}

在这个函数中，我根据出生年份作为整数来计算年龄。

public static void distributionByAge()
{
    int child = 0; //between 0-16
    int youngAdults = 0; //between 17-30
    int middleAged = 0; //between 30-55
    int oldAged = 0; //above 55

    var lines = File.ReadAllLines(@"data.csv"); // read file

    foreach (var line in lines) // Reads file line by line
    {
        string[] values = line.Split(","); // Split each value
        string birthYear = values[2]; // Birth year is value number 2 of each string/line

        int age = getAge(Int32.Parse(birthYear));

        // Check the age range
        if (age>=0 || age<=16)
        {
            // If the age is between 0 and 16 increment count
            child++;
        }
        else if (age>=17 || age<=30)
        {
            // If the age is between 17 and 30 increment count
            youngAdults++;
        }
        else if (age>=31 || age<=55)
        {
            // If the age is between 31 and 55, increment count
            middleAged++;
        }
        else
        {
            // If tge afe is above 55, increment count
            oldAged++;
        }
    }

    // Print results in percentages

    int total = child + youngAdults + middleAged + oldAged;

    Console.WriteLine("-------------------------------------------------------------------");

    Console.WriteLine("Child: ");
    Console.WriteLine(getPercentage(total, child) + "%");

    Console.WriteLine("-------------------------------------------------------------------");

    Console.WriteLine("Young Adults: ");
    Console.WriteLine(getPercentage(total, youngAdults) + "%");

    Console.WriteLine("-------------------------------------------------------------------");

    Console.WriteLine("Middle-Aged Adults: ");
    Console.WriteLine(getPercentage(total, middleAged) + "%");
    Console.WriteLine("-------------------------------------------------------------------");

    Console.WriteLine("Old-Aged Adults: ");
    Console.WriteLine(getPercentage(total, oldAged) + "%");
}

这些是我的函数，我试图读取CSV文件，获取出生年份信息，并根据它计算年龄。我必须将字符串类型转换为int，但我得到了未处理的异常和错误类型的错误。
