试试这个:

DateTime.Now.ToString("HH:mm:ss tt");

对于其他格式，您可以检查这个网站:c# DateTime格式

我认为这段代码将解决您的问题

DateTime.Now.ToString("HH:mm")

试试这个。它为我工作在3tier架构Web应用程序。

"'" + DateTime.Now.ToString() + "'"

请记住插入查询中的单引号。

例如:

string Command = @"Insert Into CONFIG_USERS(smallint_empID,smallint_userID,str_username,str_pwd,str_secquestion,str_secanswer,tinyint_roleID,str_phone,str_email,Dt_createdOn,Dt_modifiedOn) values ("
 + u.Employees + ","
 + u.UserID + ",'"
 + u.Username + "','"
 + u.GetPassword() + "','"
 + u.SecQ + "','"
 + u.SecA + "',"
 + u.RoleID + ",'"
 + u.Phone + "','"
 + u.Email + "','"
 + DateTime.Now.ToString() + "','"
 + DateTime.Now.ToString() + "')";

行尾的DateTime插入。

var CurDate= DateTime.Now;
CurDate.Hour;
CurDate.Minute;
CurDate.Millisecond

MyEmail.Body = string.Format("The validation is done at {0:HH:mm:ss} Hrs.",DateTime.Now);

可以使用{0:HH:mm:ss}、{0:HH:mm:ss。{0:DD/mm/yyy HH:mm:ss}，等等…

计算当前的datetime:

DateTime theDate = DateTime.UtcNow;

string custom = theDate.ToString("d");

MessageBox.Show(custom);
