winform中dateTimePicker自定义属性的应用
在很多winform项目中有需要使用dateTimePicker控件，对于一些自定义的格式，例如：
![](https://wkrtcs.bdimg.com/rtcs/image?w=446.00&md5sum=7bb87df0273caec90e098464c7c4e828&sign=0e2b1c27eb&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"446.00","h":"113.00","dataType":"png","c":"word/media/image1.png","imgOriW":402,"imgOriH":100})
只需要显示日期和时间字符，不需要完整的格式
首先在工具箱中拉两个![](https://wkrtcs.bdimg.com/rtcs/image?w=275.00&md5sum=7bb87df0273caec90e098464c7c4e828&sign=0e2b1c27eb&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","r":"r_14","w":"275.00","h":"338.00","dataType":"png","c":"word/media/image2.png","imgOriW":275,"imgOriH":338})
dateTimePicker控件，并且命名dateTimePicker1和dateTimePicker2.
dateTimePicker1，修改日期格式MMdd
![](https://wkrtcs.bdimg.com/rtcs/image?w=207.00&md5sum=7bb87df0273caec90e098464c7c4e828&sign=0e2b1c27eb&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","r":"r_14","w":"207.00","h":"202.00","dataType":"png","c":"word/media/image3.png","imgOriW":207,"imgOriH":202})
dateTimePicker2中时间需要可以上下调整，类似于numericUpDown用法，
![](https://wkrtcs.bdimg.com/rtcs/image?w=195.00&md5sum=7bb87df0273caec90e098464c7c4e828&sign=0e2b1c27eb&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","r":"r_14","w":"195.00","h":"203.00","dataType":"png","c":"word/media/image4.png","imgOriW":195,"imgOriH":203})
找到自定义的格式和属性并且修改showupdown为true。
