How do I solve the System.IO.FileNotFoundException?-CodePudding

I'm trying to load a picture in MonoGame (without Content.Load), But when I try to launch the project I encounter the System.IO.FileNotFoundException and I was hoping someone could tell me what I'm doing wrong.

Error message: System.IO.FileNotFoundException: 'Could not find file 'G:\Min enhet\C#\FirstMonoGameProject\bin\Debug\netcoreapp3.1\Content\Graphic\CoolBox'.'

The code where I get the error

 public Texture2D LoadTexture()
        {

   
            string fullPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location)
              "/Content/Graphic/"   "CoolBox";


            using (FileStream fileStream = File.Open(fullPath, FileMode.Open))
            {

                Texture2D myTexture2D = Texture2D.FromStream(EntityManager.graphicsDevice, fileStream);
                return myTexture2D;

            }

        }

Additional code where I call on the method (both from game1)

 protected override void LoadContent()
        {
            spriteBatch = new SpriteBatch(GraphicsDevice);
           
            coolBox.LoadTexture();

        }

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();

        spriteBatch.Draw(coolBox.LoadTexture(), new Rectangle(0, 0, 280, 210), Color.White);

        spriteBatch.End();

        base.Draw(gameTime);
    }

Thanks in advanced!

First I would add checking for the file existence using File.Exists(String) method. Also I found helpful is to use Path.Combine() method to properly create a path instead of manually concatenating strings.

CodePudding user response：

System.IO.FileNotFoundException appears when the path that you are using is wrong , it means that the file doesnt exist. Your problem cames on the variable string fullpath wich has a wrong path.

First check on your computer(windows search : windows s) that the file exists by copying there the full path. Anyway to prevent this exception you can use try catch block to display a message if the file dont exists. Other solution can be using File.Exists(path) , this way you dont throw an exception.
