Question

I want to add the value from my database to a label.

The value has a datatype varbinary(max)

string buF = dt.Rows[i]["BuF"].ToString();
Label3.Text = buF;

For this I get the output as System.Byte[] which is not the correct value.

Any suggestions?

Thanks

This sounds like a job for the BitConverter class:

string buF = BitConverter.ToString((byte[])dt.Rows[i]["BuF"]);
Label3.Text = buF;

Note that this will insert hyphens between each byte value in the output string. If you want to remove the hyphens and/or generate a different string format then you could do something like this, for example:

string buF =
    "0x" + BitConverter.ToString((byte[])dt.Rows[i]["BuF"]).Replace("-", "");
Label3.Text = buF;
