Call funxction example:
DataSetToExcel(ds.Tables[0], @"D:\ZhaoNick\Desktop\test.xls");
这次需要做一个windowServices,主要的功能就是从local db提取数据存入ftp excel file中,在提取数据成功后存入dataset中,在导入到excel时要给标题加下划线和内容设置居中时,发现报了“Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: “object”未包含“get_Range”的定义”这么一段错误,后来才发现是.net版本问题或者说是写法有问题。。不过最后还是解决了这个坑。
