Something is fundamentally wrong with your approach to work in general. Was it so difficult to look at the MSDN help page and see the right spelling? Well, take a look now:
msdn.microsoft/en-us/library/system.string.substring.aspx[^].
Please, no offense: what you really need to learn is this: Microsoft Q209354.

尝试使用以下方法将格式传递给我的电话号码,但不起作用 谁能解释 我的错误是 字符串"不包含子字符串"的定义,并且找不到找到接受字符串"类型的第一个参数的扩展方法子字符串"(您是否缺少using指令或程序集引用?) 模型
try to use the following method to pass the format to my phone number,butis not work can anybody explain the error i have is ''string'' does not contain a definition for ''substring'' and no extension method ''substring'' accepting a first argument of type ''string'' could be found (are you missing a using directive or an assembly reference?) the model
public class ViewModel { private string formatPhoneNumber(string phone) { //should return (123)456-7890 return string.Format("({0})-{1}-{2}"); } }推荐答案
总体而言,您的工作方式根本是错误的.查看MSDN帮助页面并查看正确的拼写是否如此困难?好吧,现在看看: msdn.microsoft/en-us/library/system.string. substring.aspx [ ^ ]. 请不要冒犯:您真正需要学习的是: Microsoft Q209354 .
