c#中如何用代码验证是否电子邮件(用正则)

1.引用名称空间
using System.Text.RegularExpressions;
2.代码:

string strInput=" [email protected] ";
string strExp=@"\w+([-+.]\w+)@\w+([-.]\w+)\.\w+([-.]\w+)*"
// Create a new Regex object.
Regex r = new Regex(strExp);
// Find a single match in the string.
Match m = r.Match(strInput);
if (m.Success)
{
MessageBox.Show("验证成功!");
}
