如何使用動態CRM中的查詢表達式提取插件DLL

Question

我需要使用查詢表達式來提取插件DLL。我知道我可以使用數據庫，並可以從「PluginAssemblyBase」表和「內容」列中提取它。無論如何，我可以使用查詢表達式來提取它嗎？

您必須獲取'content'屬性並使用'FromBase64String'方法來獲取原始字節。

String connectionString = @"AuthType=AD;Url=http://xyz/CRO; Domain=DEVDOMAIN; Username=user01; Password=12345"; 
CrmServiceClient conn = new CrmServiceClient(connectionString); 
IOrganizationService orgService = conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy; 
QueryExpression qExpr = new QueryExpression("pluginassembly") { ColumnSet = new ColumnSet(new string[] { "pluginassemblyid", "content" }) }; 
qExpr.Criteria.AddCondition("name", ConditionOperator.Equal, "YourAssemblyName"); 
EntityCollection entColl = orgService.RetrieveMultiple(qExpr); 
Byte[] data = Convert.FromBase64String((String)entColl[0]["content"]);
