namespace ConsoleApplication1
{
class Program
{
    static void Main(string[] args)
    {

        Console.WriteLine("Welcome to 1st program of console by ali which is marksheet...:P ;)");
        Console.WriteLine("Enter the marks of subjects..");

        Int32[] array = new int[5];

        Console.WriteLine("Enter the marks of Maths..!");
        array[0] = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the marks of Arabic..!");
        array[1] = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the marks of English..!");
        array[2] = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the marks of Science..!");
        array[3] = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the marks of Physics..!");
        array[4] = Convert.ToInt32(Console.ReadLine());

        for(Int32 i=0 i < array.Length i++)
        {
            Console.WriteLine(i + " is the obtained marks from 500..");
        }

        Console.ReadKey();
    }
}

}

Answer 1

将 for 循环更改为：

for(Int32 i=0 i < array.Length i++)
{
    Console.WriteLine(i + " is the obtained marks from 500..");
}

收件人：

for(Int32 i=0; i < array.Length; i++)
{
    Console.WriteLine(array[i].ToString() + " is the obtained marks from 500..");
}

此外，在任何语言中使用 "array" 作为变量名通常都不是好的做法。您可能希望将数组变量名称更改为更类似于 myArray 或 my_array.
