Deserialize a String with XmlSerializer

Hi,

Im trying to deserialize the string with the following content:

"<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<report>
<report-name name='Custom Adgroup Performance Report'/>
<date-range date='Mar 25, 2015-Mar 31, 2015'/>
<table>
<columns>
<column name='campaignID' display='Campaign ID'/>
<column name='adGroupID' display='Ad group ID'/>
<column name='impressions' display='Impressions'/>
<column name='clicks' display='Clicks'/>
<column name='cost' display='Cost'/>
</columns>
<row campaignID='268503015' adGroupID='19443549735' impressions='0' clicks='0' cost='0'/>
<row campaignID='268503015' adGroupID='19474365615' impressions='0' clicks='0' cost='0'/>
<row campaignID='268503615' adGroupID='19443569895' impressions='0' clicks='0' cost='0'/>
<row campaignID='268503615' adGroupID='19443570015' impressions='0' clicks='0' cost='0'/>
<row campaignID='268503615' adGroupID='19443570135' impressions='0' clicks='0' cost='0'/>
</table>
</report>"

This is my code:
The Problem is that I cant put my String directly into the Deserializer so I tried to go over XmlReader.
But this throws an Exeption "System.IO.DirectoryNotFoundException: Could not find a part of the path"

Does anybody know how to work with a string to deserialize?

`

XmlSerializer serializer = new XmlSerializer(typeof(Report));
XmlReaderSettings settings = new XmlReaderSettings();

        var reader = XmlReader.Create(stringToDeserialize);


        var list = serializer.Deserialize(reader);

    [XmlRootAttribute(ElementName = "report")]
    public class Report
    {
        [XmlElementAttribute("table")]
        public ReportTable Table { get; set; }
    }

    public class ReportTable
    {
        [XmlElementAttribute("columns")]
        public Columns Table { get; set; }


        [XmlArray("row")]
        [XmlArrayItemAttribute("campaignID")]
        public string[] campaignID { get; set; }

        [XmlArrayItemAttribute("adGroupID")]
        public string[] adGroupID { get; set; }

        [XmlArrayItemAttribute("impressions")]
        public string[] impressions { get; set; }

        [XmlArrayItemAttribute("clicks")]
        public string[] clicks { get; set; }

        [XmlArrayItemAttribute("cost")]
        public string[] cost { get; set; }

    }

    public class Columns
    {
        [XmlArray("column")]
        [XmlArrayItemAttribute("name")]
        public string[] name { get; set; }
        [XmlArrayItemAttribute("display")]
        public string[] display { get; set; }
    }
