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**

我有错误

“ SqlDateTime溢出。必须在1/1/1753 12:00:00 AM和12/31/9999 11:59:59 PM之间。”

有什么解决方案？
