c# - sqldatetime溢出异常c#.NET

Question

string con = ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString;

        SqlConnection cn = new SqlConnection(con);
        string insert_jobseeker = "INSERT INTO JobSeeker_Registration(Password,HintQuestion,Answer,Date)"
      + " values (@Password,@HintQuestion,@Answer,@Date)";

        SqlCommand cmd = new SqlCommand();
        cmd.Connection = cn;
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = insert_jobseeker;

 cmd.Parameters.Add(new SqlParameter("@Password", SqlDbType.VarChar, 50));
            cmd.Parameters["@Password"].Value = txtPassword.Text;
            cmd.Parameters.Add(new SqlParameter("@HintQuestion", SqlDbType.VarChar, 50));
            cmd.Parameters["@HintQuestion"].Value = ddlQuestion.Text;
            cmd.Parameters.Add(new SqlParameter("@Answer", SqlDbType.VarChar, 50));
            cmd.Parameters["@Answer"].Value = txtAnswer.Text;

            **cmd.Parameters.Add(new SqlParameter("@Date", SqlDbType.DateTime));
            cmd.Parameters["@Date"].Value = System.DateTime.Now**

我得到的错误是

"SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."

解决这个问题的方法是什么？

Answer 1

尝试将 SQL Server 端的 @Date 的类型更改为 DATETIME2(7)

然后在您的代码中改用这一行:

cmd.Parameters.Add(new SqlParameter("@Date", SqlDbType.DateTime2)); 

如图所示，您的代码看起来没问题，但由于本地化问题或您的区域/时间设置有问题，转换可能会发生某些事情，因此请查看这是否有效。
