二、string -> DateTime string dtString = “2009-10-12 00:12:05”; DateTime dt = DateTime.Parse(dtStr); //方式一 DateTime dt2 = Convert.ToDateTime(dtStr); //方式二 1. 2. 3. 当然DateTime也有多种表示方式(非格式化成字符串类型),如: dt.ToFileTimeUtc(); //127756704859912816 dt.ToLocalT...
dateTime =DateTime.Now;this.textBox1.Text = day[Convert.ToInt32(dateTime.DayOfWeek)]; }string[]day=newstring[]{"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};//} 3字符串转换为DateTime 用DateTime.Parse(string)方法,符合"MM/dd/yyyy HH:mm:ss"格式的字符串, 如果是...
DateTime t1 = Convert.ToDateTime(time1); DateTime t2 = Convert.ToDateTime(time2); TimeSpan ts1=t2-t1; string tsMin=ts1.Minutes.ToString(); TimeSpan ts11=new TimeSpan(t1.Tick); TimeSpan ts22=new TimeSpan(t2.Tick); string diff=ts22.Subtract(ts11).TotalMinutes.ToString(); Subtract:表...
DateTime => 字符串时间 :ToString()方法以及几个重载,另外ToXxString方法。 字符串时间 => DateTime : ① DateTime.Parse和DateTime.TryPase两个静态方法。② Convert.ToDateTime("2013-03-21") 其实系统预定义的这些常见类型,比如Int32、DateTime等,特定类型和字符串直接的相互转换都有上面3种模式。 20.简述C#...
DateTimedateTime; dateTime=DateTime.Now; this.textBox1.Text = day[Convert.ToInt32(dateTime.DayOfWeek)]; } string[]day=newstring[]{"星期日","星期一","星期二","星期三","星期四 ","星期五","星期六"};// } 3字符串转换为DateTime
最近需要把“20121010”转换为“2012-10-10”格式,直接用Convert.ToDateTime("20121010"),系统报错“未被识别的DateTime类型”。 解决方法: 一、DateTime.ParseExact string str = "20121010"; IFormatProvider ifp = new CultureInfo("zh-CN", true);
The following code shows how to convert DateTime to long date string. Example usingSystem;/*fromwww.java2s.com*/classSample {publicstaticvoidMain() { DateTime myDateTime =newSystem.DateTime(2001, 5, 16, 3, 2, 15); Console.WriteLine(myDateTime.ToLongDateString()); } ...
通过下面的实例，可以让大家清楚如何使用枚举类型：创建一个控制台应用程序，通过使用枚举类型来判断当前系统日期是星期几，代码如下：namespace ConsoleEnum{ class Program { static void Main(string[] args) { int k = (int)DateTime.Now.DayOfWeek;//获取当前日期是星期几的数字返回值 switch...
public static String getCurrentTimeSpan() { TimeSpan ts = DateTime.Now.ToUniversalTime() - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc); string timeSpan = Convert.ToInt64(ts.TotalSeconds).ToString(); return timeSpan; ...
Convert.ToDateTime("2005/12/2222:22:22").ToString("yyyy/MM/ddHH ss") "2005/12/2222:22:22" (7)inti=123; doublej=123.45; strings=string.Format("i:{0,-7},j:{1,7}",i,j); //-7表示左对齐,占7位 this.textBox1.Text=s;
