Now, let's create a spreadsheet. If you are reading from a single sheet (by default the first one in the workbook), create a list with response data. How to read data of an Excel file using C#? OK,One of the more difficult concepts to grasp about Excel VSTO programming is that you don't refer to cells like an array, Worksheet[0][0] won't give you cell A1, it will error out on you. Even when you type into A1 when Excel is open, you are actually entering data into Range A1. Therefore you refer to cells as Named Ranges. Here's an example: Excel. Worksheet sheet = workbook. Sheets["Sheet. 1"] as Excel. Worksheet. Excel. Range range = sheet. Range("A1", Missing. Value). You can now literally type: range. Text // this will give you the text the user sees. Value. 2 // this will give you the actual value stored by Excel (without rounding). If you want to do something like this: Excel. Range range = sheet. Range("A1: A5", Missing. Value). if (range. Excel. Range r in range. Text. string value = r. Value. 2. There might be a better way, but this has worked for me. The reason you need to use Value. Value is because the Value property is a parametrized and C# doesn't support them yet. As for the cleanup code, i will post that when i get to work tomorrow, i don't have the code with me, but it's very boilerplate. You just close and release the objects in the reverse order you created them. You can't use a Using() block because the Excel. Application or Excel. Workbook doesn't implement IDisposable, and if you don't clean- up, you will be left with a hanging Excel objects in memory. Note: If you don't set the Visibility property Excel doesn't display, which can be disconcerting to your users, but if you want to just rip the data out, that is probably good enough. You could Ole. Db, that will work too. I hope that gets you started, let me know if you need further clarification. I'll post a complete here is a complete sample: using System. System. IO. using System. Reflection. using NUnit. Framework. using Excel. Tools = Ms. Office. Excel = Microsoft. Office. Interop. Excel. Tests. [Test. Fixture]. Excel. Single. public void Process. Workbook(). string file = @"C: \Users\Chris\Desktop\Test. Sheet. xls". Console. Write. Line(file). Excel. Application excel = null. Excel. Workbook wkb = null. Excel. Application(). Excel. Tools. Office. Util. Open. Book(excel, file). Excel. Worksheet sheet = wkb. Sheets["Data"] as Excel. Worksheet. Excel. Range range = null. Range("A1", Missing. Value). string A1 = String. Empty. if( range != null ). A1 = range. Text. To. String(). Console. Write. Line("A1 value: {0}", A1). Exception ex). //if you need to handle stuff. Console. Write. Line(ex. Message). finally. Excel. Tools. Office. Util. Release. RCM(wkb). Excel. Tools. Office. Util. Release. RCM(excel). I'll post the functions from Excel. Tools tomorrow, I don't have that code with me either. Edit. As promised, here are the Functions from Excel. Tools you might need. Excel. Workbook Open. Book(Excel. Application excel. Instance, string file. Name, bool read. Only, bool editable. Links) {. Excel. Workbook book = excel. Instance. Workbooks. Open(. file. Name, update. Links, read. Only. Type. Missing, Type. Missing, Type. Missing, Type. Missing, Type. Missing. Type. Missing, editable, Type. Missing, Type. Missing, Type. Missing. Type. Missing, Type. Missing). return book. Release. RCM(object o) {. System. Runtime. Interop. Services. Marshal. Release. Com. Object(o). To be frank, this stuff is much easier if you use VB. NET. It's in C# because I didn't write it. VB. NET does option parameters well, C# does not, hence the Type. Missing. Once you typed Type. Missing twice in a row, you run screaming from the room! As for you question, you can try to following: http: //msdn. VS. 8. 0). aspx. I will post an example when I get back from my meeting.. Edit: Here is an examplerange = sheet. Cells. Find("Value to Find". Type. Missing. Type. Missing. Type. Missing. Type. Missing. Excel. Xl. Search. Direction. Next. Type. Missing. Type. Missing, Type. Missing). range. Text; //give you the value found. Here is another example inspired by this site: range = sheet. Cells. Find("Value to find", Type. Missing, Type. Missing,Excel. Xl. Look. At. xl. Whole,Excel. Xl. Search. Order. xl. By. Columns,Excel. Xl. Search. Direction. Next,false, false, Type. Missing). It helps to understand the parameters. P. S. I'm one of those weird people who enjoys learning COM automation. All this code steamed from a tool I wrote for work which required me to process over 1.
