从Windows Phone 7应用程序发送电子邮件

Question

In my Windows Phone 7 application I want to send an e-mail where the message body should contain the data from my previous page in my application. Previously I just integrated the e-mail facility like this:

private void Image_Email(object sender, RoutedEventArgs e)
{
    EmailComposeTask emailComposeTask = new EmailComposeTask();

    emailComposeTask.Subject = "message subject";
    emailComposeTask.Body = "message body";
    emailComposeTask.To = "recipient@example.com";
    emailComposeTask.Cc = "cc@example.com";
    emailComposeTask.Bcc = "bcc@example.com";
    emailComposeTask.Show();
}

But I was not able to test this in my emulator. Now in the body part I want my data from the previous page. So how to do this?

Updated code:

if (this.NavigationContext.QueryString.ContainsKey("Date_Start"))
{
    //if it is available, get parameter value
    date = NavigationContext.QueryString["Date_Start"];
    datee.Text = date;
}

if (this.NavigationContext.QueryString.ContainsKey("News_Title"))
{
    //if it is available, get parameter value
    ntitle = NavigationContext.QueryString["News_Title"];
    title.Text = ntitle;
}

if (this.NavigationContext.QueryString.ContainsKey("News_Description"))
{
    ndes = NavigationContext.QueryString["News_Description"];
    description.Text = ndes;
}

Now what do I write in the message body? I am not able to test it as I do not have a device. Can i pass in the values like this:

emailComposeTask.Body = "title, ndes, date";

Answer 1

I think the code is correct. if you want to pass body from previous page, you need to pass it when page navigation. and set emailComposeTask.Body = yourPassedValue. like this:

var date;
var title;
var ndes;

emailComposeTask.Body = title + "," + ndes + "," + date;

您需要像这样编辑邮件正文行：

emailComposeTask.Body = title+" "+ ndes+" "+ date;

Answer 3

You cannot test sending mail in the emulator since you don't have a proper email account set up. Nor you could set it up in the emulator.

The Body property is a string so you can put inside pretty much anything you want.

Using the following code will only generate a string containing exactly that:

emailComposeTask.Body = "title, ndes, date";

So the result mail will have a body containing "title, ndes, date" as a text. If you want to replace the title with the value from the local variable named title , you need to use the following syntax:

emailComposeTask.Body = string.Format("{0}, {1}, {2}", title, nodes, date);
