C#设置系统日期和时间

C#设置系统日期和时间的代码分享,使用C#代码设置系统日期和时间的程序开发步骤如下:

1)为了使用DllImportAttribute类,需要引入命名空间:

using System.Runtime.InteropServices;

2)自定义类SetSystemDateTime用于设置系统时间。代码如下:

public class SetSystemDateTime
{

[DllImportAttribute( "Kernel32.dll" )]

public static extern void GetLocalTime(SystemTime st ) ;

[DllImportAttribute( "Kernel32.dll" )]

public static extern void SetLocalTime(SystemTime st ) ;

}


3)自定义类SystemTime用于定义日期时间类。代码如下:

[StructLayoutAttribute( LayoutKind.Sequential)]
public class SystemTime

{

public ushort vYear;

public ushort vMonth;

public ushort vDayOfWeek;

public ushort vDay;

public ushort vHour;

public ushort vMinute;

public ushort vSecond;

}

4)选择一个时间,单击“设置系统新日期时间”按钮,在该按钮的Click事件下,调用自定义类SetSystemDateTime和SystemTime,修改当前系统日期时间。代码如下:

private void button2_Click(object sender, EventArgs e)

{

//设置系统当前日期时间

if (MessageBox.Show("您真的确定更改系统当前日期和时间吗?", "信息提示", MessageBoxButtons.OK) == DialogResult.OK)

{

DateTime Year = this.dateTimePicker1.Value;

SystemTime MySystemTime = new SystemTime();

SetSystemDateTime.GetLocalTime(MySystemTime);

MySystemTime.vYear = (ushort)this.dateTimePicker1.Value.Year;

MySystemTime.vMonth = (ushort)this.dateTimePicker1.Value.Month;

MySystemTime.vDay = (ushort)this.dateTimePicker1.Value.Day;

MySystemTime.vHour = (ushort)this.dateTimePicker2.Value.Hour;

MySystemTime.vMinute = (ushort)this.dateTimePicker2.Value.Minute;

MySystemTime.vSecond = (ushort)this.dateTimePicker2.Value.Second;

SetSystemDateTime.SetLocalTime(MySystemTime);
}
}
