• .NET Development XmlSerializer on properties and indexers ... how do they work?

  I have to use XmlSerializer to serialize a class and I've found big problems serializing properties and indexers. I assumed that if you serialize a class with public properties (or an indexers) containing a field, even private, the serialization process would serialize that field too assuming it is needed to that public property. This is not the case ... For example I want to serialize the following class: [Serializable] public class Test { readonly int[] a; // same results with private readonly int b; // same results with private public Test(int[] v1, int b) { a = v1; b = v2; } public Test() : this(new int[] {10, 10}, 50) { } public int this[int i] { get { return a[ i ]; } set { a[ i ] = value; } } pub ...Show All

• .NET Development XML Error associated with mscoree.dll

  My solution consists of a dll to interface with ESRI's ArcMap application as well as two executables, an XML document (AddPLSS.xml) and an install package. It compiles and installs without any problems, but when I try to open ArcMap, I get the following error: XML Error: The system cannot locate the resource specified. In (failed) mscoree.dll/AddPLSS.xml. The XML file itself seems to be included in the dll and the install package. It ends up in the right place on the client machine. In fact, this application was working well until fairly recently. I did add one of the executables to the solution, but I never changed anything related to the XML file. I cannot find any reference to this specific error anywhere via Google or MSDN. I ...Show All
