Question

我有一个程序是.net。当我执行程序时我得到这个例外。该程序应该与财务打印机通信。

使用CLSID检索组件的COM类工厂 {741F1E1B-0D59-4F59-A775-3E1B13721638}因以下原因失败错误：80040154未注册类（HRESULT异常： 0x80040154（REGDB_E_CLASSNOTREG））。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using FiscPrinter = FiscPrnSys.IFiscPrnIface;
using System.Runtime.InteropServices;
public class Class1
{
    public List<String> salesITems = new List<String>();
    public String user;
    public String shop;
    public double total;
    public double subtotal;
    public String tax;
    public short data = (short) 8;
    public short parity = (short)0;
    public short stopbit = (short)1;

    public void PrintBon()
    {
        FiscPrnSys.IFiscPrnIface FiscPrinter = new FiscPrnSys.FiscPrnIface();     (this     where the program is bringing this exemption)
        FiscPrinter.Connect("COM2", 9600, data, parity, stopbit);
        FiscPrinter.TestPrinter((short)48, "1,0,1", "HELLO");
        FiscPrinter.Sale("TEST ITEM 1", "A", 2, 2, 0);
        FiscPrinter.Sale("TEST ITEM 1", "A", 2, 2, 0);
        FiscPrinter.Sale("TEST STOCK ITEMS ZERO VAT", "B", 2, 2, 0);
        FiscPrinter.Sale("Cooking Fat Always Ultra", "B", 2, 2, 0);
        FiscPrinter.PrintFiscalText("TEST STOCK ITEMS VATABLE"); 
        FiscPrinter.Sale("001000124", "A", 2, 2, 0);
        FiscPrinter.PrintFiscalText("Kimbo 1 Kg");
        FiscPrinter.Sale("598699484", "A", 5, 5, 0);
        FiscPrinter.PrintFiscalText("Tily Cooking Fat");
        FiscPrinter.Sale("484949404", "A", 2, 2, 0);
        FiscPrinter.Sale("Always ULtra", "A", 10, 2, 0);
        FiscPrinter.Disconnect();
    }
    public void setUser(String user)
    {
        this.user = user;
    }
    public void setShop(String shop)
    {
        this.shop = shop;
    }
    public void addSaleItem(String item)
    {
        salesITems.Add(item);
    }
    public void setDouble(double pTotal)
    {
        this.total = pTotal;
    }
    public void setSubTotal(double sTotal)
    {
        this.subtotal = sTotal;
    }
    public void setTax(String pTax)
    {
        this.tax = pTax;
    }
 }

这个类由另一个类

调用

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using IncortexLibrary;

 class Program
 {
    static void Main(string[] args)
    {
        Class1 printer = new Class1();
        printer.PrintBon();
    }
 }

输出：

这已经让人头痛。我已经在system32中注册了文件.dll文件，但它仍然给我带来了问题。这意味着我在错误的程序中使用该程序。打印机显示为null。请帮助因为我试图浏览网页但是没有得到解决方案

这通常是由于权限问题在注册表中设置了完全控制
