最近在搞.NET web 程序报表时，发现ReportViewer 工具栏为英文。经过查找资料研究，提供一下解决方案。
第一步：在项目中创建一个目录(文件夹)，名为：App_Code,
第二步：创建一个CS控制器，名称为：ReportViewerLanguageZh.继承自IReportViewerMessages。其实业务逻辑比较简单，就是实现托管配置。
public class ReportViewerLanguageZh : IReportViewerMessages
引用文件就不列举了，根据VS提示，添加引用类。
第三步:复制以下内容到此控制器中：
public class ReportViewerLanguageZh : IReportViewerMessages
{
#region IReportViewerMessages Members

public string BackButtonToolTip
{
get { return ("后退"); }

第三步：找到项目的配置文件Web.config,找到appSettings节点，
向此节点增加以下key属性
<add key= "ReportViewerMessages" value= "XXXX.App_Code.ReportViewerLanguageZh,App_Code" />
将XXXX替换为你的ReportViewerLanguageZh控制中的命名空间namespace前缀，即App_Code之前的部分.
OK,搞定，运行跑起来看看。如下图：
