错误 System.ArgumentException："Keyword not supported: "字符集“。”

Question

我正在尝试使用 dataGridView 将一些数据插入我的数据库并填充它的单元格，但我收到以下错误 System.ArgumentException: "Keyword not supported: "charset"."

这是我的代码：

        public string connect = "Server=localhost;Database=hardlight;Uid=root;pwd=platon6993;charset=utf8";

string StrQuery;
                
                    using (SqlConnection conn = new SqlConnection(connect))
                    {
                        using (SqlCommand comm = new SqlCommand())
                        {
                            comm.Connection = conn;
                            conn.Open();
                            for (int i = 0; i < dataGridView1.Rows.Count; i++)
                            {
                                StrQuery = @"INSERT INTO rabota VALUES ("
                                    + dataGridView1.Rows[i].Cells["id"].Value + ", "
                                    + dataGridView1.Rows[i].Cells["name"].Value + ", "
                                    + dataGridView1.Rows[i].Cells["dadada"].Value + ");";
                                comm.CommandText = StrQuery;
                                comm.ExecuteNonQuery();
                            }
                        }
                    }

我能做什么？请帮助

删除字符集，你的连接字符串应该是这样的

  public string connect = "Server=localhost;Database=hardlight;Uid=root;Pwd=platon6993;";

您的查询字符串应包含 ' ' 作为字符串值

 StrQuery = $"INSERT INTO rabota VALUES ( {dataGridView1.Rows[i].Cells["id"].Value},'{dataGridView1.Rows[i].Cells["name"].Value}', '{dataGridView1.Rows[i].Cells["dadada"].Value}')";
