如何在段落中替换电子邮件地址，假设它现在是一个字符串，带有名字？例如xx@yahoo.com.my = xx，.com，.ae

输入=“联系abc@yahoo.com或defg@hotmail.eu了解更多详情”

输出=“联系Abc或Defg了解更多详情”

Answer 1

既然你要求正则表达式，我会给你一个。

Regex regex = new Regex(@"(\.|[a-z]|[A-Z]|[0-9])*@(\.|[a-z]|[A-Z]|[0-9])*");
foreach (Match match in regex.Matches(inputString))
{
    // match.Value == "xx@yahoo.com.my"
    string name = match.Groups[1]; // "xx"
    string domain = match.Groups[2]; // "yahoo.com.my"
}

Answer 2

int end = myString.IndexOf('@');

string name=myString.Substring(0, end);

试试这样。

您可以在这里参考子串函数＆gt;＆gt;

Answer 3

Sting input = "contact abc@yahoo.com or defg@hotmail.eu for more details";
String pattern = @"(\S*)@\S*\.\S*";
String result = Regex.Replace(input , pattern , "$1");

Answer 4

public static string ReplaceEmail(string emailBody) {
        string scrubbedemailBody = emailBody;
        Regex regex = new Regex(@"(\.|[a-z]|[A-Z]|[0-9])*@(\.|[a-z]|[A-Z]|[0-9])*");
        scrubbedemailBody = regex.Replace(scrubbedemailBody, match => {
            return new string(' ', match.Length);
        });
        return scrubbedemailBody;
    }
