我使用反射加載兩個程序集,然後使用它們中的幾個類型。加載程序集後,加載一個類型,然後用Activator實例化一個類型,當試圖調用「LoadFromXml」方法時,程序集上出現FileNotFound異常。這是以前工作,我不明白什麼改變。另外,我可以從創建的實例中獲取一個屬性,而不會出現問題。它只在調用方法「LoadFromXml」時拋出異常。我剛剛成功加載程序集後找不到文件
private static object CheckForVersion(int version, string constructFilePath, string utilityFilePath)
{
if (!System.IO.File.Exists(constructFilePath) || !System.IO.File.Exists(utilityFilePath) || version < 7) return null;
var utilAssembly = System.Reflection.Assembly.LoadFile(utilityFilePath);
var constructAssembly = System.Reflection.Assembly.LoadFile(constructFilePath);
var InfoManager = utilAssembly.GetType(String.Format("{0}.InfoManager", utilAssembly.FullName.Split(',')[0]));
var ExecutionServerPropertiesConstructType = constructAssembly.GetType(String.Format("{0}.ExecutionServerPropertiesConstruct", constructAssembly.FullName.Split(',')[0]));
string dbFolder = (string)(InfoManager.GetProperty("ServerDatabaseFolder").GetValue(null, null));
if (Directory.Exists(dbFolder) == true)
{
string FilePath = Path.Combine(dbFolder, @"ExecutionServer.config.xml"); //DONT LOCALIZE
dynamic theServerProperties = Activator.CreateInstance(ExecutionServerPropertiesConstructType);
theServerProperties.LoadFromXml(FilePath);
var retVal = new

InstalledProductVersion = version,
ServerGuid = (string)InfoManager.GetField("SERVER_GUID").GetValue(null),
WorkflowRootnodeGuid = (string)InfoManager.GetField("WORKFLOW_ROOTNODE_GUID").GetValue(null),

};
return Newtonsoft.Json.JsonConvert.SerializeObject(retVal);

return null;
