尝试初始化对象时，为什么会出现System.TypeInitializationException？

Question

我在尝试初始化对象时遇到异常。这是例外：

A first chance exception of type 'System.TypeInitializationException' occurred in GeneticProcessorGUI.exe

这是对函数的调用，似乎抛出错误：

ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv fitnessCalc =
            new ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv("localhost", "CP20141118", "CP20141118", "dbo_DataSourceFraud", 10, 5);

我尝试在函数中添加一些日志，但它没有打印任何日志，所以我认为在执行任何代码之前它在调用中失败了。

这是构造函数代码：

 public FitnessAurocCv(string asServerConnectionString, string asDatabaseName, string dataSourceView, string tableName, int numberOfFolds, int foldsToTest)
        {
            _dataSourceView = dataSourceView;
            _tableName = tableName;
            _numberOfFolds = numberOfFolds;
            _foldsToTest = foldsToTest;
            _dataBaseName = asDatabaseName;

            _availableVars = CreateVariablesList();

            _asServer = new Server();

            _log.Debug("Connecting to " + asServerConnectionString);

            _asServer.Connect(asServerConnectionString);

            _asDatabase = _asServer.Databases[asDatabaseName];

            _log.Debug("Connected OK.");

        }

可能导致这种情况的原因是什么？我在另一个应用程序中使用完全相同的调用，它工作正常，我没有在网上找到任何有用的东西，并且可以真正使用你的帮助。

以防万一，以下是导致问题的整个类的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using ModelingAutomation.MR.Fitness.SSAS;

namespace GeneticProcessorGUI
{

    public class Controller
    {

        private GeneticProcessorGUI gpgui;

        public void startGUI(){

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            gpgui = new GeneticProcessorGUI(this);
            Application.Run(gpgui);
        }

        public void ProcessPosibleVariables(string server, string database, string datasourceview, string tablename)
        {
            //MessageBox.Show("PPV");
            try
            {
                //ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv fitnessCalc =
                //new ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv(server, database, datasourceview, tablename, 10, 5);
                ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv fitnessCalc =
                new ModelingAutomation.MR.Fitness.SSAS.FitnessAurocCv("localhost", "CP20141118", "CP20141118", "dbo_DataSourceFraud", 10, 5);
                MessageBox.Show("before call");
                Dictionary<string, string> vars = fitnessCalc.CreateVariablesListFromSource();
                MessageBox.Show("" + vars.ToArray().Length);
                foreach (KeyValuePair<string, string> entry in vars)
                {
                    // do something with entry.Value or entry.Key
                    MessageBox.Show(entry.Value + " , " + entry.Key);
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }


        }


    }
