Visual Studio错误无法在int上调用方法

Question

Just Trying to insert some simple data into a table but every time I try I get the error "cannot call method on int". Here is my code, thanks for any help data types in table are int for cinema Id and nvarchar(50) for ReviewText

protected void BtnSubmitReview_Click(object sender, EventArgs e)
    {
        try
        {           
            System.Data.SqlClient.SqlConnection sqlConnection1 = new System.Data.SqlClient.SqlConnection("RegistrationConnectionString");

            System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
            cmd.CommandType = System.Data.CommandType.Text;

            cmd.CommandText = "INSERT INTO ReviewText (ReviewText.CinemaID, ReviewText.ReviewText) VALUES (1, 'NorthWestern')";
            cmd.Connection = sqlConnection1;

            sqlConnection1.Open();
            cmd.ExecuteNonQuery();
            sqlConnection1.Close();

            Response.Write("Your Review was saved");                
        }
        catch (Exception ex)
        {
            Response.Write("Error" + ex.ToString());

Answer 1

You don't need to qualify the column names in your INSERT statement with the table name. Use this as your SQL:

INSERT INTO ReviewText (CinemaID, ReviewText) VALUES (1, 'NorthWestern')

Also, If you are looking for a connection string in your application/web.config you can't just put the key in the SqlConnection constructor to get the actual connection string. You have to use the ConfigurationManager class to get value, which would look something like this:

var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["RegistrationConnectionString"].ConnectionString);

Answer 2

Your code has a problem and I don't know if this problem is the root of your exception or not, please first edit it to this and then tell us the result:

    //you dont need to repeat table name in insert command's columns
    cmd.CommandText = "INSERT INTO ReviewText (CinemaID, ReviewText) VALUES (1, 'NorthWestern')";

also it is highly recommended to use SqlConnection via this way:

using(System.Data.SqlClient.SqlConnection sqlConnection1 = new System.Data.SqlClient.SqlConnection("RegistrationConnectionString"))
{
        System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
        cmd.CommandType = System.Data.CommandType.Text;

        cmd.CommandText = "INSERT INTO ReviewText (CinemaID, ReviewText) VALUES (1, 'NorthWestern')";
        cmd.Connection = sqlConnection1;

        sqlConnection1.Open();
        cmd.ExecuteNonQuery();
        sqlConnection1.Close();

}
