问题 I want to create an XML DOM programmatically using the System.Xml.Linq objects. I'd rather not parse a string or load a file from disk to create the DOM. In C# this is easy enough, but trying to do this in PowerShell does not seem possible. Option 1 : Doesn't work $xlinq = [Reflection.Assembly]::Load("System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089") $el = new-Object System.Xml.Linq.XElement "foo" This gives the following error: new-Object : Cannot convert

阅读更多关于 XElement.XPathEvaluate not evaluating exponential numbers correctly

问题 In my C# Program, I am loading a System.Xml.Linq.Xelement variable with a portion of an XML file I'm trying to parse and feeding it various XPaths to evaluate values for using the XPathEvaluate() method. My challenge is that my XML has some numbers stored as exponential numbers and the XPath is ignoring them even though I'm reading that XPath 2.0 should allow for these being understood to be numbers. A sample would look as follows: XML ( childNode ): <Parent> <Vals id="Val1"> <abc>1.8</abc> <

In the About-dialog I can clearly see that the System.XML library is loaded. How can I make it accessible to my project?
