After initializing byte array in constructor, it is returning null in the object

Question

My code:

public class UplaodedFile
{
    public UploadedFile File = null;
    public string Description = null;
    public string OriginalFileName = null;
    public byte[] inputStream ; 

    public UplaodedFile(UploadedFile file, string desc, string FileName, byte[] inputStream)
    {
        File = file;
        Description = desc;
        OriginalFileName = FileName;
        inputStream = inputStream;
    }
}

I am creating an object as below:

UplaodedFile uploadedfile = new UplaodedFile(uploaded_file, description, originalFileName, file_contents);

and when I try to access the uploadedfile.inputStream, I am getting null.

What am I doing wrong?

Rename your field to InputStream which should be done anyway because it's public. But you should not have public fields, instead use properties. Read why properties matter — Tim Schmelter

You are referring to constructor's argument in constructor

Instead of

inputStream = inputStream;

You need to write

this.inputStream = inputStream;

By setting

inputStream = inputStream;

you only assign to the parameter inputStream. As your class field is also named inputStream you need to tell the compiler to set it by using this:

this.inputStream = inputStream;
