    <p>I am creating a simple MVC4 application</p> <p>I have a automapper </p> <pre><code> Mapper.CreateMap&lt;SourceClass, DestinationClass&gt;() .ForMember(dest =&gt; dest.IntphoneNo, opt =&gt; opt.MapFrom(src =&gt; src.Stringphoneno)); </code></pre> <p><strong>IntphoneNo</strong> is of DataType <strong>int</strong> ( IntphoneNo is an variable of my class <code>Person</code>) Source attribute <strong>Stringphoneno</strong> is of Datatype <strong>string</strong>.</p> <p>When i am mapping , i am getting follwoing error.</p> <blockquote> <p>An exception of type 'AutoMapper.AutoMapperMappingException' occurred in AutoMapper.dll but was not handled in user code</p> </blockquote> <p>But when i am changing the Dataype of <strong>IntphoneNo</strong> from <strong>int</strong> to <strong>string</strong> then my program is running successfully.</p> <p>Unfortunately i cant change the Datatype inmy model</p> <p>Is theer any way to change Datatupe in mapping .. Something like below </p> <pre><code>.ForMember(dest =&gt; dest.IntphoneNo, opt =&gt; opt.MapFrom(src =&gt; src.Int32(Stringphoneno)); </code></pre> <p>After some research I came one step futher ..<br> If my StringPhoneNo is = 123456<br> then follwoing code is working. I dont need to parse it to string </p> <pre><code>Mapper.CreateMap&lt;SourceClass, DestinationClass&gt;() .ForMember(dest =&gt; dest.IntphoneNo, opt =&gt; opt.MapFrom(src =&gt; src.Stringphoneno)); </code></pre> <p>but when my StringPhoneNo is = 12 3456 ( there is a <strong>space after 12</strong>) then my code is not working. Is there any way to trim spaces in Stringphoneno (<strong>Stringphoneno</strong> i am geting from webservice) in automapper.</p> <p>Something like below..</p> <pre><code>Mapper.CreateMap&lt;SourceClass, DestinationClass&gt;() .ForMember(dest =&gt; dest.IntphoneNo, opt =&gt; opt.MapFrom(src =&gt; src.Trim(Stringphoneno))); </code></pre>

    1. COI wouldn't advise storing phonenumbers(i assume) as ints, you'll lose the international/regional zero prefix numbers. Also, some numbers can be very long. (unless you use a int64) With 11 numbers you got some overflow problems.

    2. CO@JeroenvanLangen I came across the same kind of advice at one point when someone pointed out that we shouldn't be using the money sql type to store money and should instead use decimal. I had a good laugh when I pointed out that we worked in dollars and if we ever had an order where the purchase actually was larger than the money type, I would do the order by hand, we were a small wine company. Not really relevant, just a story I always liked.

    3. CO@Yuriy Faktorovich - But finding a International phone number larger than 10 digit is much easier than scoring an order larger than max money-type :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
