Question

我编写了一个插件，该插件在异常中抛出OrganizationService对象，以检查它是否包含任何组织内容。但我遇到了例外。我附上以下内容并期待您的指导。 TIA !!

代码：

protected void ExecutePostRequestforApprovalCreate(LocalPluginContext localContext)
        {
            if (localContext == null)
            {
                throw new ArgumentNullException("localContext");
            }

            IPluginExecutionContext context = localContext.PluginExecutionContext;
            IOrganizationService service = localContext.OrganizationService;

            var serviceContext = new OrganizationServiceContext(service);

            throw new ArgumentException("Exception sent:"+service.ToString());
}

例外：

错误通常是由服务器和Visual Studio项目之间的Microsoft.Xrm.Sdk SDK版本不一致引起的。

删除引用，重建项目并添加正确的SDK版本作为参考。再次重建并使用插件注册工具导入。
