Question

SqlConnection cnn = new SqlConnection();
cnn.ConnectionString = "Data Source=.;Database = deptStore;Integrated Security = true;";
cnn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "insert into Employee values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" + TextBox6.Text + "','" + TextBox7.Text + "','" + TextBox8.Text + "','" + TextBox9.Text + "','" + TextBox10.Text + "','" + TextBox11.Text + "','" + TextBox12.Text + "','" + TextBox13.Text + "')";
cmd.Connection = cnn;
cmd.ExecuteNonQuery();
Response.Write("Record Save");
cnn.Close();

但是我得到了以下错误：

SqlConnection cnn = new SqlConnection（）; cnn.ConnectionString =“Data Source = .; Database = deptStore; Integrated Security = true;”;

            cnn.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.CommandText = "insert into Employee values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" + TextBox6.Text + "','" + TextBox7.Text + "','" + TextBox8.Text + "','" + TextBox9.Text + "','" + TextBox10.Text + "','" + TextBox11.Text + "','" + TextBox12.Text + "','" + TextBox13.Text + "')";
            cmd.Connection = cnn;
            cmd.ExecuteNonQuery();
            Response.Write("Record Save");
            cnn.Close();

但是我得到了以下错误：用户代码
