            tempfile = null;
            tempfilesr = null;
        }
}

当我点击第一种形式的Button1时 - ＆gt;出现第二种形式。但是当我在第二种形式中单击按钮1时，我有一个FileNotFound异常。我做错了什么？

Answer 1

非常模糊的样本......
为什么要尝试用assamblykub()来呼叫assemblyDomain.DoCallBack(assamblykub);？这种跨域调用的方法只需将assemblyDomain.DoCallBack(assamblykub);与assamblykub()复制，然后就可以运行了

从另一个刚编译的程序集编译程序集
