我的代码中有一句：Excel.Application app=new Excel.Application(),这个引用了Microsoft.Office.Interop.Excel.dll,我在自己的电脑上运行没问题，可是生成的软件装到别人没有office的电脑上就报错了：
还有类似的报错不过都是COM组件的问题，我查了一下网上对这个报错的解决方式中首先确保电脑中必须有office，可是如果用这个软件的话还得再装一个office的话（我能想到的也就是把office打包进安装包里），那就有点动作太大了，求问各位大佬这种情况有没有不用安装office的解决途径？

看你是需要操作Excel，那么使用LinqToExcel是可以的，或者使用第三方库，比如NPOI之类的。
我刚才找了下，很久以前写了个方法，是winform的，你看看有帮助没。
