c# - SQL Server 插入

Question

我有一个简单的两字段表单，将其数据存储在数据库中。由于某种原因，它不起作用。我已验证连接字符串有效，因为它在我制作的另一个项目中使用。

我没有包括第一个类的开头或其页面加载。

代码:

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        string Name = txtName.Text;
        string Description = txtSpecial.Text;
        string method = string.Format(
            "INSERT INTO RbSpecials (Name,Description,Active) VALUES ('{0}','{1}','1')",
            Name,
            Description);
        RbConfiguration mySql = new RbConfiguration();
        try
        {
            mySql.Sql_Connection(method);
        }
        catch
        {

        }
    }
}

public class RbConfiguration
{
    string DbConnectionString = "System.Configuration.ConfigurationManager.ConnectionStrings['RBConnectionString'].ConnectionString";

    public void Sql_Connection(string queryString)
    {
        SqlConnection conn = new SqlConnection(DbConnectionString);
        SqlCommand cmd = new SqlCommand(queryString, conn);
        conn.Open();

        conn.Close();
    }
}

Answer 1

你永远不会execute你的 SQL 命令:

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

而且你的连接字符串是错误的(去掉双引号):

string DbConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["RBConnectionString"].ConnectionString;
