问题
I have an xml file. I want to read it and after that i want to set values of that xml file to an object that i created and finally i want to add these objects to a list. The problem is, after adding the list when i print the some object values, all of theme are same and belong to last <current id="3"> node. Here is the xml file and implementation
XML:
<currents>
<current id="1">
<currentCode>1</currentCode>
<currentName>c1</currentName>
<currentAddress>a1</currentAddress>
<currentTel>02321111111</currentTel>

</current>
<current id="2">

You don't have to read the document manually.You can use XmlSerializer.
1)Copy the xml dodument to the clipboard (The content of the document)
2)Use the function PasteSpecial in VisualStudio.Edit->Paste Special->Paste XML AS Classes
Or take these classes
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
