C# expecting brackets when none needed and other errors I can't seem to find solution to-CodePudding

I'm making Class that will read json data from files, but for some unknown reason, I keeep geting errors. I really hope it's not only stupid mistake on my side.

My Code: - Not working

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Blackjack
{
    class LeaderBoard
    {
        LeaderBoard(string fileName)
        {
            public string filename = fileName;
            if (!File.Exists(fileName))
            {
                File.Create(fileName);
            }
            private string contents = System.IO.File.ReadAllLines(fileName);
        }
    }
}

My Code - Working

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Blackjack
{
    class LeaderBoard
    {
        LeaderBoard(string fileName)
        {
           
            if (!File.Exists(fileName))
            {
                File.Create(fileName);
            }
            
        }
    }
}

I really don't know what is wrong... where is that missing semicolon?

CodePudding user response：

You cannot use access modifiers inside a class member, they can only be applied to the class members themselves:

class LeaderBoard
{
    public string filename;
    private string[] contents;

    LeaderBoard(string fileName)
    {
        filename = fileName;
        if (!File.Exists(fileName))
        {
            File.Create(fileName);
        }
        contents = System.IO.File.ReadAllLines(fileName);
    }
}

CodePudding user response：

Problem is that you are using public and private in the constructer of your class. Also you should define the contents as a string array.

namespace Blackjack
{
    class LeaderBoard
    {
        LeaderBoard(string fileName)
        {
            string filename = fileName;
            if (!File.Exists(fileName))
            {
                File.Create(fileName);
            }
            string[] contents = System.IO.File.ReadAllLines(fileName);
        }
    }
}

            if (new FileInfo(fileName).Length == 0) {
                return;
            }
            using (var sr = new StreamReader(fileName)) {
                fileContent = sr.ReadToEnd();
            }
            return fileContent;
        }
    }
}

Try this :)
