i using the following function :

Image found in path D:/person.jpg

C#

public static byte[] ImageToBinary(string _path)  
{  
FileStream fS = new FileStream(_path, FileMode.Open, FileAccess.Read);  
byte[] b = new byte[fS.Length];  
fS.Read(b, 0, (int)fS.Length);  
fS.Close();  
return b;  
}

How to receive the value returned from function ImageToBinary in textbox1 ?

This question does not make sense. A binary array is not text, so putting it in a text box would just produce unreadable garbage.

I need to convert image from byte array to binary string 0 or 1

You should explain this ...
What kind of sense does it make for you if you convert each byte of an image to it's binary value (as string) to display it in a Textbox ?

You have all the parts, all you need to do is loop through the byte array and convert each number to binary representation.

Keep in mind there is usually a max length on a text box that you might have to manually overcome (make it multi-line / increase the max length, etc.

C#

public static byte[] ImageToBinary(string _path)  
{  
    FileStream fS = new FileStream(_path, FileMode.Open, FileAccess.Read);  
    byte[] b = new byte[fS.Length];  
    fS.Read(b, 0, (int)fS.Length);  
    fS.Close();  
    return b;  
}

public static void SetText(string _path) {
    byte[] b = ImageToBinary(_path);
    
    StringBuilder binary = new StringBuilder();

    foreach (var bb in b) {
         binary.Append(Convert.ToString(bb, 2));
    }

    textBox1.Text = binary.ToString(); 

}
