如何计算逗号“，"的数量?在TextBox.text中?

问题描述

伙计们，

我使用VS.NET 2008在VB.NET中编写了一个小程序，对数字进行排序.

我从TextBox1.text中输入用逗号分隔的数字，播放某种算法，然后单击按钮，在TextBox2.text中显示排序后的值.

现在我想将数字限制为仅20个位置(例如32,1,6,32,12,21,21,54,675,8,4,3,2,9,0,21,21,21,43,744 )在TextBox1.text中，所以我想到了数逗号:laugh:

我可以这样做吗?还是有更好的方法来实现这一目标?


谢谢

Hi guyz,

I wrote a tiny programme in VB.NET using VS.NET 2008 to sort numbers.

I take the input of numbers separated by commas from TextBox1.text, play some algorithm then by clicking a button, display the sorted values in TextBox2.text.

NOW i want to restrict the numbers to be only 20 positions (eg. 32,1,6,32,12,21,21,54,675,8,4,3,2,9,0,21,21,21,43,744) in the TextBox1.text and so i thought of counting the commas :laugh:

Can I do that, how? OR is there any better way to achieve this?


Thanks
