Question

我有一个c＃app。当我从visual studio正常运行这个应用程序或使用双击到.exe文件时，一切都是文件和工作正确。但我必须从sql server执行.exe文件。我使用xp_cmdshell，我有这个错误：

未处理的异常：System.IO.FileNotFoundException：无法加载文件或程序集'Newtonsoft.Json，Version = 7.0.0.0，Culture = neutral， PublicKeyToken = 30ad4fe6b2a6aeed'或其中一个依赖项。该系统找不到指定的文件。

我的应用代码就是这个

using System.Collections.Generic;

Answer 1

您需要服务器上提供的Newtonsoft.json.dll

简单：保留bin文件夹中的所有文件以及可执行文件，确保引用属性＆＃34; Copy Local＆＃34;对于Newtonsoft.Json

，设置为true

高级：或者，将Newtonsoft.Json.dll添加到全局程序集缓存（GAC）

不知道如何向GAC添加dll？ Check this article out了解如何使用Powershell
