将具有所有条件格式设置规则的Excel文件导入到epplus [英] Importing excel file with all the conditional formatting rules to epplus
问题描述
我有一个excel文件，其中包含大量数据以及基于单元格中的值的图标集和数据栏.看起来像这样:
I have an excel file which contains lots of data along with icon sets and data bars based on the values in the cell. It looks like this:
我想将此Excel工作表与条件格式一起导入.有图书馆吗?我经历了这个 http://www.sitecorecleveland.com/resources/blogs-posts/easy_excel_interaction_pt6 ，但它仅导入数据，而不格式化.
I want to import this excel sheet along with the conditional formatting. Is there any library for this?? I went through this http://www.sitecorecleveland.com/resources/blogs-posts/easy_excel_interaction_pt6 but it only imports data not format.
如果不可能的话，epplus中是否有代码将这些图标集包含在excel工作表中.我可以有箭头，交通信号灯等，但是不能.
If that's not possible is there code in epplus to have these iconsets in excel sheet. I can have arrows, traffic lights, etc but not these.
推荐答案
我不认为EPP支持自定义条件格式，该条件格式存储为Excel文件xml中的工作簿扩展名".您可以将包含自定义格式的"extLst"的xml节点从一个工作表复制到另一个工作表.只要确保您不想复制的节点中的cond格式xml旁边没有其他内容，在这种情况下，您将只需要选择所需的子节点即可.
I dont think EPP supports custom conditional formatting which are stored as "Workbook Extensions" in the xml of the Excel file. You could copy the xml node of the "extLst" which contains the custom formatting from one worksheet to another. Just make sure there is nothing else beside the cond formatting xml in the node that you do not want copied in which case you will have to select only the child nodes you want.
为了进行测试，我创建了以下Excel工作表(temp.xlsx)，仅对值进行了copy.paste并保存到新文件(temp2.xlsx):
To test, i created the following excel sheet (temp.xlsx), did a copy.paste of values only and saved to a new file (temp2.xlsx):
然后运行以下命令，并成功复制了格式:
Then ran the following and it successfully copied the formatting over:
public void Custom_Condition_Copy_Test()
{
//http://stackoverflow.com/questions/28493050/importing-excel-file-with-all-the-conditional-formatting-rules-to-epplus
//File with custom conditional formatting
var existingFile = new FileInfo(@"c:\temp\temp.xlsx");
//Copy of the file with the conditonal formatting removed
var existingFile2 = new FileInfo(@"c:\temp\temp2.xlsx");
using (var package = new ExcelPackage(existingFile))
using (var package2 = new ExcelPackage(existingFile2))
{
//Make sure there are document element for the source
var worksheet = package.Workbook.Worksheets.First();
var xdoc = worksheet.WorksheetXml;
if (xdoc.DocumentElement == null)
return;
//Make sure there are document element for the destination
var worksheet2 = package2.Workbook.Worksheets.First();
var xdoc2 = worksheet2.WorksheetXml;
if (xdoc2.DocumentElement == null)
return;
//get the extension list node 'extLst' from the ws with the formatting
var extensionlistnode = xdoc
.DocumentElement
.GetElementsByTagName("extLst")[0];
//Create the import node and append it to the end of the xml document
var newnode = xdoc2.ImportNode(extensionlistnode, true);
xdoc2.LastChild.AppendChild(newnode);
package2.Save();
}
}
可能想在其中尝试一下，但这应该可以让您接近.
Might want to put some try's in there but this should get you close.
更新:基于OP的评论.
UPDATE: Based on OPs comment.
如果您希望能够添加自定义条件格式而不需要包含该条件格式的原始文件，我会看到两个选项.
If you want to be able to add the custom conditional format without the need of the original file that contains it, I see two options.
选项1 ，您可以更正确"地进行操作，并使用DocumentFormat.OpenXml命名空间.但是，这将要求您具有可用的Office Open XML库，这可能会很简单，也可能不太简单，具体取决于您在其中运行的环境.您可以从这里
Option 1, you do it the more "correct" way and use the DocumentFormat.OpenXml namespace. BUT, this would require you to have the Office Open XML library available which may or may not be so easy depending on the environment you are running this in. You can get it from here http://www.microsoft.com/en-us/download/details.aspx?id=30425 and it comes with a Reflection tool that can generate the code you want which gets you this:
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;
using DocumentFormat.OpenXml;
using X14 = DocumentFormat.OpenXml.Office2010.Excel;
using Excel = DocumentFormat.OpenXml.Office.Excel;

....
worksheet1.Append(worksheetExtensionList1);
选项2 将按照您的要求执行并执行字符串操作.这要容易得多，但是有点脏，因为您是在弄乱字符串而不是对象，但是如果您需要设置的唯一内容是看起来并不那么糟糕的单元格范围.我用上面的测试方法用= extensionlistnode.OuterXml提取了字符串:
Option 2 would be to do as you are asking and perform string manipulation. This is much easier but it is a slightly dirty in that you are messing with strings rather then objects but if the only thing you need to set is the cell range that doesnt seem so bad. I used the test method above to extract the string with = extensionlistnode.OuterXml:

datatable.Columns.Add(new DataColumn("Col1", typeof(int)));

datatable.Columns.Add(new DataColumn("Col3", typeof(int)));
for (var i = 0; i < 20; i++)
{
var row = datatable.NewRow();
row["Col1"] = i;
row["Col2"] = i * 10;
row["Col3"] = i * 100;
datatable.Rows.Add(row);
