& # 39; System.TypeInitializationException& # 39;在以前工作的代码上抛出

我的代码以前工作得很好，但现在当我运行它;它会抛出这个异常:

类型为"System"的未处理异常。TypeInitializationException"内附加信息:类型'varBank'的初始化器抛出异常。

更奇怪的是，除了添加这个类之外，我什么也没改变:

public class readParameters
{
    public static void readLog(int start, int end)
    {
        for (int x = start; x < end; x++)
        {
        }
    }
    public static void nextLine()
    {
        string[,] logArr = new string[4, 5];
    }
}

问题行在

下面的块中突出显示。

          varBank.logInput = Console.ReadLine();

            Console.WriteLine("Enter Read Parameters: ");
            int i = 1;
            while (++i > 0)

                string CommandInput = Console.ReadLine();
