This the .NetFrame work error list

C#

An exception of type 'System.Data.SqlClient.SqlException' occurred in Brp.Core.dll but was not handled in user code Additional information: Implicit conversion from data type varchar to varbinary(max) is not allowed. Use the CONVERT function to run this query.

This is my model:

C#

//[Required]
       public byte[] Passport { get; set; }

       /*[Required]
       [DataType(DataType.ImageUrl)]
       public string BusinessLogo { get; set; }*/

       //[Required]
       public byte[] BusinessLogo { get; set; }

       [ScaffoldColumn(false)]
       //[Column]
       public string ImageMimeType { get; set; }

       [ScaffoldColumn(false)]
       //[Column]
       public string ImageMimeType2 { get; set; }

This my sequel

C#

SqlConnection con = new SqlConnection(@"Data Source=(localdb)\v11.0;Initial Catalog=Bpr;Integrated Security=True");
               SqlCommand cmd = new SqlCommand();
               cmd.CommandText = String.Format("Insert into Payer(User_Id, PayerName, BusinessName,PhoneNumber,BusinessMobile,PayerAddress,NumberOfStaff,RegDate,DateOfBirth,LocationLatLog,Passport,StateOfOrigin,BusinessLogo, ImageMimeType, ImageMimeType2) values('" + payer.User_Id + "','" + payer.PayerName + "','" + payer.BusinessName + "','"
                + payer.PhoneNumber + "','"+payer.BusinessMobile + "','" + payer.PayerAddress + "','" +payer.NumberOfStaff + "','" +
                payer.RegDate + "','" + payer.DateOfBirth + "','" + payer.LocationLatLog + "','" + payer.Passport + "','"
                + payer.StateOfOrigin + "','" + payer.BusinessLogo + "','" + payer.ImageMimeType + "','" + payer.ImageMimeType2+ "')");
                cmd.Connection = con;
            try
            {
                con.Open();
                cmd.ExecuteNonQuery();
                con.Close();
                return "Success";
            }
        
            catch (Exception es)
            {
                throw es;
            }

Try to Execute Query with parameter

C#

// Assuming "conn" is an open SqlConnection
using(SqlCommand cmd = new SqlCommand("INSERT INTO mssqltable(varbinarycolumn) VALUES (@binaryValue)", conn))
{
    // Replace 8000, below, with the correct size of the field
    cmd.Parameters.Add("@binaryValue", SqlDbType.VarBinary, 8000).Value = arraytoinsert;
    cmd.ExecuteNonQuery();
}
