我在之前的博客中介绍过如何为Microsoft Dynamics CRM 2011 安装语言包,安装了不同的语言包后,用户可以选择使用不同的界面语言。我在本文中介绍一下如何获得当前用户使用的界面语言。

 

(一) 前端

如果是使用JScript获得当前用户使用的界面语言,比如在Form的OnLoad事件处理器中,可以用

context.getUserLcid()

该方法返回一个数字,即为Language ID,比如美国英语是1033,中文简体为2052。完整的Locale ID Values表,大家可以参见http://msdn.microsoft.com/en-us/library/ms912047(WinEmbedded.10).aspx

 

下面在account form的OnLoad事件中测试一下:

if (typeof (AccountLibrary) == "undefined") { 
    AccountLibrary = { __namespace: true }; 
}


AccountLibrary = { 
    Name: "AccountLibrary", 
    OnLoad: function () { 
        var languageid = Xrm.Page.context.getUserLcid(); 
        alert(languageid); 
    } 
} 

打开一个account,我们能看到弹出的languageid的对话框:

(二) 后端

运行在服务器上的代码(C#或者VB)该如何获得当前用户的界面语言呢?

首先要获得当前用户的ID,我们以插件(plugin)为例,当前用户为context.UserId。获得当前用户的ID之后该怎么办,在CRM 4中,我们使用RetrieveUserSettingsSystemUserRequest来获得用户设置(User Settings),但是在CRM 2011中,虽然这个Message还被支持,但这只是基于向后兼容的考虑,在SDK中清楚地写着该Message已经是Deprecated,我们应该使用RetrieveMultiple方法来获得相应的usersettings Entity,所以还在使用RetrieveUserSettingsSystemUserRequest的同学,最好改用RetrieveMultiple方法。下面我们在一个测试插件中来演示一下:

public class Plugin : IPlugin 
{ 
    #region IPlugin Members 
    private int? GetCurrentUserLanguageId(IOrganizationService service, ITracingService tracingService, Guid userid) 
    { 
        QueryExpression mySavedQuery = new QueryExpression 
        { 
            ColumnSet = new ColumnSet("systemuserid", "uilanguageid"), 
            EntityName = "usersettings", 
            Criteria = new FilterExpression() 
            { 
                FilterOperator = Microsoft.Xrm.Sdk.Query.LogicalOperator.And, 
                Conditions = 
                {       
                    new ConditionExpression 
                    { 
                        AttributeName = "systemuserid", 
                        Operator = ConditionOperator.Equal, 
                        Values = {userid} 
                    } 
                } 
            } 
        };

        EntityCollection ec = service.RetrieveMultiple(mySavedQuery); 
        tracingService.Trace("Debug: usersettings is retrieved"); 
        if (ec != null && ec.Entities != null && ec.Entities.Count > 0 && ec.Entities[0].Contains("uilanguageid")) 
        { 
            tracingService.Trace("Debug: usersettings contains uilanguageid"); 
            return (int)(ec.Entities[0]["uilanguageid"]); 
        } 
        else 
        { 
            tracingService.Trace("Debug: usersettings does not contain uilanguageid"); 
            return null; 
        } 
    }

    public void Execute(IServiceProvider serviceProvider) 
    { 
        // Obtain the execution context from the service provider. 
        IPluginExecutionContext context = 
            (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

        // Get a reference to the organization service. 
        IOrganizationServiceFactory factory = 
            (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); 
        IOrganizationService service = factory.CreateOrganizationService(context.UserId);

        // Get a reference to the tracing service. 
        ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

        try 
        { 
            if (context.MessageName == "Create") 
            { 
                Entity entity = (Entity)context.InputParameters["Target"]; 
                int? languageid = GetCurrentUserLanguageId(service, tracingService, context.UserId);                    
                throw new InvalidPluginExecutionException(string.Format("languageid = {0}", languageid.ToString())); 
            } 
        } 
        catch (FaultException<OrganizationServiceFault> ex) 
        { 
            tracingService.Trace("Error: {0}", ex.ToString()); 
            throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex); 
        } 
        catch (Exception ex) 
        { 
            tracingService.Trace("Error: {0}", ex.ToString()); 
            throw; 
        } 
    }

    #endregion 
} 

创建一个account,可以看到抛处的异常,错误信息中包含了language id

总结:如果在前端获得当前用户的界面语言,可以用context.getUserLcid(),在后端可以用RetrieveMultiple方法来获得systemuserid为当前用户ID的usersettings Entity,然后获得usersettings Entity的uilanguageid。
