谢谢

Thanks

试试这个代码..

Try this code..

private bool ValidateUrl(string url)
{
    Uri validatedUri;

    if (Uri.TryCreate(url, UriKind.Absolute, out validatedUri)) //.NET URI validation.
    {
        //If true: validatedUri contains a valid Uri. Check for the scheme in addition.
        return (validatedUri.Scheme == Uri.UriSchemeHttp || validatedUri.Scheme == Uri.UriSchemeHttps);
    }
    return false;
}
