如果您想将一个13位数字拆分为4个数字，那么一定要这样做.

如果这只是进行某些验证或输入的方式，那么我建议您使用带遮罩的文本框进行输入.
面具TextBox ASP.NET控件 [增强的文本框控件 [

If you want to split one 13 digit number into 4 numbers, then surely Split is the way.

If it''s just the way for some validation or input taking then I would suggest you to use a masked textbox to take the input.
Mask TextBox ASP.NET Control[^]
Enhanced Textbox Control[^]

There are few similar control based article here at code project itself.
This sort of control would restrict only given number of digits, no less no more in a specified format. Change it as per your need.

您需要使用验证程序来强制使用格式.使用string.Split方法将其转换为单独的数字.

You need to use a validator to enforce your format. Use the string.Split method to turn it into seperate numbers.
