Save Dataset As Excel File C#

Can you told us step by step and let us clear about what do you want, and then we can know how to help you. And for so much data in application, I suggest you not use the complex data structure to store the data but use the array instead of those complex data structure to store the data or operate the data. Use array will save you more time than use those complex data structure. If there’s anything unclear, please feel free to let me know.

Hi all, I'm using 'Microsoft.Office.Interop.Excel' for loading the excel datas. I've more than a lakh row in a single Excel. I'm comparing 2 excels. Both excel have email Id columns.

I am using below code to send mail MailMessage mail = new MailMessage(); mail.Attachments.Add(new Attachment(ms, 'example.xls', 'application/vnd.ms-excel')); ms (Memory stream) has data, but the attachment was blank. Used this code to read to memory stream (given by u) MemoryStream ms = new MemoryStream (); StreamWriter my Writer = new StreamWriter ( ms ); I could create excel file with data using below code. StreamWriter myWriter = new StreamWriter ( path + “ Report. Xls ”); But attachment is blank.

I want to compare a column in A with Column in B, where B is another Excel File which contains more than 1000 rows.

Yaya, There are a few ways that you can go about doing this. The most obvious way I would think of doing this would be to use the OLE DB provider for Excel and try to use an OleDbDataAdapter, calling Update. If you are using a version of Excel that supports XML, then you can just take the dataset that the grid is bound to and then save the XML contents. If that doesn't work, then you could take the data set, and write out to a CSV file (cycling through the rows and columns). If you want the native Excel format, then you will have to access Excel through automation and populate the sheet yourself.

I want to do this is faster manner. Please let me know if you are unclear with the question.

Thanks in advance.

I am a 29 year old software Web Developer from Hyderabad, India. I have been working since approximately age 25. Where as in IT Development industry since 27. I am Microsoft Certified Technology Specialist. I have taught myself in development, beginning with Microsoft's technologies ASP.NET, Approximately 3 years ago, I was given an opportunity to work as a freelance in the tech field.

I want it to be in a readable format, not just comma delimited, so non-equal spacing between columns on each row if that makes sense. Here is an example of what I mean: Column1 Column2 Column3 Some info Some more info Even more info Some stuff here Some more stuff Even more stuff Bits and bobs Note: I only have one DataTable within my DataSet so no need to worry about multiple DataTables. EDIT: When I said 'readable' I meant human-readable.

In this how can the array be used. How can you compare 2 columns when u store in array?

Hi, I am using C# lnaguage to develp my windows (exe)applications. I would like to export the dataset to multiple sheets in 1 excel.I had search online but find no solution in this.The only one which is working is VB language.I try to export the second sheets but the output is the data in first sheet is cleared out.

Best Regards, Suderson P If this is helpful, please Vote as Helpful If this answers your doubt, Mark As Answered. I had read your solution, and I think use the datatable is enough to do that job. If we want to do that job use array, then we need to design a data structure ourselves because you want to compare the two sheets. This will be a complex job for such project. Use array is also like you use a datatable, but it is only a structure we design that table structure with Multidimensional arrays. If you want to research this topic, and you also have not enough such experience, then I suggest you to read some data structure topic book.

While not a.NET implementation, you may find that the plug-in TableTools may be highly effective depending on your audience. It relies upon flash which shouldn't be a problem for most cases of needing to actually work in-depth and then want to record tabular information. The latest version appears to support copying to clipboard, into a CSV, '.XLS' (really just a tab-delimited file named.xls), to a PDF, or create a printer friendly page version with all rows displayed and the rest of your page's contents hidden. I found the extension on the DataTables site here: The download is available in the plug-ins (extras) page here: It supposedly is downloaded as a part of DataTables (hence the phrase 'Extras included in the DataTables package') but I didn't find it in the download I have been using. Seems to work wonderfully!

Now I am working as a web developer where my roles make me purely in web based technology solutions which manage and control access to applications and patient information stored in legacy systems, client-server applications. I too had an opportunity to train some IT professionals with technical skills in development area. Which became my passion. I have worked on various.NET framework versions(2.0, 3.5, 4.0) and have been learning every new technology being introduced.
