Prepend the foreach with a null check: if (xmlNode.Attributes != null) foreach (...)

Replace node.Text = (xmlNode.OuterXml).Trim(); With: node.Text = (xmlNode.OuterXml).Trim(); foreach (XmlAttribute attribute in xmlNode.Attributes) node.Text += string.Format( {0}=\{1}\ attribute.Name attribute.Value);

It ok like this : foreach ( XmlAttribute attribute in xmlNode.Attributes) { if ( attribute.Name == name || attribute.Name == title || attribute.Name == id ) node.Text += string .Format(  {0}=\{1}\  attribute.Name  attribute.Value); } ____ Big thanks for all

Like this : if (xmlNode.Attributes != null ) foreach ( XmlAttribute attribute in xmlNode.Attributes) { node.Text += string .Format(  {0}=\{1}\  attribute.Name == id && attribute.Name == name  attribute.Value); }

pritaeas · Answer

You can just add a check within the attributes loop (.Name should match id or name) or specifically search for those two attributes .Attributes is an associative array but you need to add null checks.

No  but no preblem Maybe  if we can choose what attribute we can show  it's possible to do it ? for exemple we show just id and name ?

pritaeas · Answer

With a lot of attributes perhaps they are just not visible. Do they show if you make your treeview wider?

am using the if (xmlNode.Attributes != null ) foreach ( XmlAttribute attribute in xmlNode.Attributes) { node.Text += string .Format(  {0}=\{1}\  attribute.Name attribute.Value); } before the foreach ( XmlNode childNode in xmlNode.ChildNodes) { } then it's seems Ok ... Just when i have a lot of attributes  i didn't had it all ( it's normal for a treeview ? )

I delete it ?

pritaeas · Answer

Is that perhaps because you use node.Text = xmlNode.OuterText ?

Nbl Bz · Answer

No I have the same thing like my first code ... with the attributes and values of childs written 2 time. something like this : // NO ATTRIBUTE // NO ATTRIBUTE id=121 x=2 y=0 // AS THE ATTRIBUTE VALUE id =131 x=3 y=0

pritaeas · Answer

Not sure what you've tried but it should be something like this I think: foreach ( XmlAttribute attribute in xmlNode . Attributes ) { var treeNode = new TreeNode(attribute.Name); node.Nodes.Add(treeNode); }

Nbl Bz · Answer

I did it ... I dont know what i can do in the code here  I did the same think as childNode BUT don't work ...

pritaeas · Answer

Every XmlNode has an Attributes property. You can loop through the values: foreach ( XmlAttribute attribute in xmlNode . Attributes ) { // code here }
