如何使用文本框输入获取VB.NET 2012中数字的百分比值？

例如：

4％= blah blah

2.5％=等等等等

2,500 * 2.5 ％= blah blah

，值2,500将在文本框中输入，2.5％将自动乘以输入。



我尝试了什么：



尚未尝试任何东西。我只想先问一下，因为我要开始我们的顶点项目。



提前谢谢！

For example:
4% = blah blah
2.5% = blah blah
2,500 * 2.5% = blah blah
and the values 2,500 will be inputted in textbox and 2.5% will be automatically multiplied to the input.

What I have tried:

not yet tried anything. I just want to ask first because I'm going to start our capstone project.

Thanks in advance!
