当我得到的值为 42,000 美元时，我如何比较并断言字符串大于 1000 美元。如何将此字符串转换为整数？

Question

string carPrice = driver.FindElement(By.XPath("//body/main[1]/article[1]/section[1]/section[1]/section[4]/div[1]/div[1]/div[1]/div[1]/div[2]/div[1]/div[1]/h3[1]")).Text;
string basePrice = "USD1000";

carPrice 是动态值，包含货币和逗号，例如 USD42,000

Answer 1

如果您的定价格式是固定的，您可以使用此 //USD42,000

char[] delimiterChars = {',','U','S','D'};
string[] values =carPrice.Split(delimiterChars);
string join = string.Join("", values);
int price = int.parse(join);

Answer 2

<块引用>

int price = int.parse(join);

以上应该是：

int price = int.Parse(join);

Parse 只是一个简单的大写 P。

Answer 3

这里有几种语言扩展方法可以提供帮助，忽略数组扩展，我已经有几个这样的方法了。
