如何分割字符串，每个字分配到一个新的变量？ [英] How to split a string and assign each word to a new variable?

问题描述

我在做一个信用卡处理形式。有问题的字段名称：（第一个和最后一个）

你会一些C＃代码的样子，将采取文字从一个文本框，并把它分解，然后分配每个字（在此情况下的姓和名）分成两个新的字符串

例如 txtName.Text =李四

拆分后

 字符串FNAME =约翰; 
 
串LName的=李四; 
  

解决方案

您可以在字符或字符串文本分成一个字符串数组，然后拉出名称的各个部分从数组中。像这样：

 的String [] = nameParts txtName.Text.Split（''）; 
 
串的firstName = nameParts [0]; 
串的lastName = nameParts [1]; 
  

但是，为什么不只是有一个单独的文本框的名称各部分？如果有人有什么把他们的全名在文本框中（即你有三部分，而不是两个）。

I'm making a credit card processing form. The field in question is Name: (first and last).

What would some C# code look like that would take the text from a text box and split it, then assign each word (in this case first and last name) into two new strings?

E.g. txtName.Text = "John Doe"

After split

string fName = "John";

string LName = "Doe";

解决方案

You can split the text on a character or string into a string array, and then pull the individual parts of the name out of the array. Like so:

string[] nameParts = txtName.Text.Split(' ');

string firstName = nameParts[0];
string lastName = nameParts[1];

But why not just have a separate text box for each part of the name? What if somebody puts their full name in the text box (i.e. you'd have three parts, not just two).
