Object Reference not set to an instant of the object 3

[seabaz2000]

Hi
I keep getting the error "Object Reference not set to an instant of the object" with the following piece of code

XmlNode model = modelDoc.SelectSingleNode(strXPath);

strName = (string)model.Attributes["name"].Value;

not quite sure what is wrong with it.
Regards

where do you instantiate modelDoc. And wich of the two lines gives the error.

Here is modelDoc

XmlDocument modelDoc = new XmlDocument();
            modelDoc.LoadXml(modelList);

            string strXPath = "//Model[@modelID='" + strModelId + "']";
            XmlNode model = modelDoc.SelectSingleNode(strXPath);

The problem piece of code seems to be

strName = (string)model.Attributes["name"].Value;

Thanks for the help

I think it should be String not string and is it model that is null or is it model.attibutes["name"] that is null.

try

strName = model.Attributes["name"].Value.ToString();

the cast could apply to the model, and a string doesn't have an Attribute.

Either model is null or the attribute "name" does not exist returning a null, as chrissie1 pointed out.

PS. Attribute[x].Value returns string so no need to cast.
