A field initializer cannot reference the non-static field, method, or property 'name'-CodePudding

I'm a c# begginer and my code generates the CS0236 error, I've created a class with a LvlData struct that contains a couple of variables and a readLvl function that takes the directory of a text file and returns a LvlData based on that.

However, when trying to use it (public LvlData CurrentLevelData = readLvl("../Level/Def/lvl.txt");) it throws an A field initializer cannot reference the non-static field, method, or property 'name'. error.

Here's the LevelManager class:

 class LevelManager
    {
        public LevelManager()
        {
           
        }

        public struct LvlData
        {
            public LvlData(int width, int height, string tiledata,string colisiondata,string flag = "0")
            {
                Width = width;
                Height = height;
                TileData = tiledata;
                CollisionData = colisiondata;
                Flag = flag; //Deafult 0 Beacuse we sometimes don't have it
            }

            public int Width { get; }
            public int Height { get; }
            public string TileData { get; }
            public string CollisionData { get; }
            public string Flag { get; }
        }
        public LvlData readLvl(string dir)
        {
            int w, h;
            string tiled, colliiond, f;

            // Read the file 
            string[] lines = System.IO.File.ReadAllLines(dir);

            w = int.Parse(lines[0]);
            h = int.Parse(lines[1]);

            tiled = lines[2];
            colliiond = lines[3];
            f = lines[4];

            LvlData deta = new LvlData(w, h, tiled, colliiond, f);

            return deta;
        }

        public LvlData CurrentLevelData = readLvl("../Level/Def/lvl.txt");

        
}

CodePudding user response：

you have to move a method call to the constructor

 class LevelManager
    {
      public LvlData CurrentLevelData {get; set;}

       public LevelManager()
        {
           CurrentLevelData = readLvl("../Level/Def/lvl.txt");
        }

or make the method and property static, but it doesn't make much sense

public static LvlData CurrentLevelData {get; set; } = readLvl("../Level/Def/lvl.txt");

public static LvlData readLvl(string dir)
{
.....
}
