如何將圖像插入數據庫？

Question

public void InsertAnImage(Guid i) 
{ 
    StringBuilder sb = new StringBuilder(); 

    sb.Append(""); 

    Stream stream = FileUpload1.FileContent; 
    StreamReader reader = new StreamReader(stream); 

    string myConnectionString = AllQuestionsPresented.connectionString; 
    using (SqlConnection conn = new SqlConnection(AllQuestionsPresented.connectionString)) 
    { 
     // sample query with parameters to insert into db 
     string sqlQuery = "INSERT INTO [UserProfile] (UserID, Picture) Values (@userId, @picture)"; 
     // conn is your db connection 
     SqlCommand command = new SqlCommand(sqlQuery, conn); 
     // creating parameters 
     SqlParameter paramId = new SqlParameter("@userId", SqlDbType.Int, 4); 
     paramId.Value = 45; 
     // you picture parameter, and assigning its the value 
     SqlParameter paramPicture = new SqlParameter("@picture", SqlDbType.Binary, myImage.Length);// red line here 
     paramPicture.Value = myImage;// red line here 
     // adding params to command 
     command.Parameters.Add(paramId); 
     command.Parameters.Add(paramPicture); 
     // then execute your command 
     command.ExecuteNonQuery(); 
    } 
}
