采纳答案by Sergey Berezovskiy
string address = "[email protected]";
string name = address.Split('@')[1].Split('.')[0];
name = name.Substring(0,1).ToUpper() + name.Substring(1); // Mycompanyname
Another option to get name is regular expression:
获取名称的另一个选项是正则表达式：
var name = Regex.Match(address, @"@([\w-]+).").Groups[1].Value

To get rid of the @ and everything before that, you would use something like this in your particular case:
要摆脱 @ 和之前的所有内容，您可以在特定情况下使用类似的内容：
string test = "[email protected]";
test = test.Substring(test.IndexOf('@')+1, test.IndexOf(".") -(test.IndexOf('@')+1));
MessageBox.Show(test);
And thisexplains how to make the first letter a capital, which you would use after you strip out the @ and .com parts.
而这解释了如何使第一个字母大写，你带出来的@和.com部分之后，你会使用。

Just another variant
只是另一个变种
var name = new MailAddress("[email protected]").Host.Split('.').First();
name = name.First().ToString().ToUpper() + String.Join("", name.Skip(1));
回答by KMC
string email = "[email protected]";
int startIndex = email.IndexOf( "@" );
int endIndex = email.IndexOf( ".", startIndex );
string domain = email.SubString( startIndex + 1, endIndex );
string domain = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(domain);
That will return Mycompanyname
这将返回Mycompanyname
