将图像字节类型从数据库显示到DataGridview C＃中

Question

Good Morning. I am Learning C# and I got a problem. I have my datagridView with some rows and columns. So, I want to display to my datagridView image but, when do it, in the column "Imagem", show me "matriz byte[]", instead of my image.

The type of my "imagem" in my database is "Varbinary(MAX)". So, have something like 0Xffd8ff0001............ in my database.

My code to load my data into datagridView is below. the name of my DatagridView is "tabelAplicFerr":

private void AplicadoresFerramentasControl_Load(object sender, EventArgs e)
    {

        try
        {
            SqlConnection con = new SqlConnection(Login.conectData);
            con.Open();
            DataSet dsFerramentas = new DataSet();
            SqlDataAdapter daFerramentas = new SqlDataAdapter("SELECT Ferramenta_ID,Imagem, Nome_Afinação, Vedante, Data_Criação, Observações, Utilizador FROM Ferramentas " +
                "JOIN FormasCravação ON FormasCravação.Cravação_ID = Ferramentas.Cravação_ID " +
                "JOIN TipoAfinação ON TipoAfinação.Afinação_ID = Ferramentas.Afinação_ID", con);

            dsFerramentas.Clear();
            daFerramentas.Fill(dsFerramentas, "Ferramentas");
            tabelAplicFerr.DataSource = dsFerramentas;
            tabelAplicFerr.DataMember = "Ferramentas";

            con.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

In my "SqlDataAdapter daFerramentas", I have in select "imagem". I get matrix byte[]", instead of my image.

How can I solve this problem?

I am using Visual Studio 2013, and SQL server 2008.

Hope you can help me. Thank you.

Answer 1

I got the answer.

I went to my datagridView design, and I simply put a column with Type imageColumn. follow the printscreen to see more details.

Click to add new column and after that I choose DatagrideViewImageColum. In my datagridView now show the image.
