I am facing a problem wherein, whenever I am trying to export a large recordset to excel (over 50k records) I am getting the System.OutOfMemoryException. I want to know a couple of things :
1. How do I handle this exception as try - catch does not seem to work?
2. I am pasting sample code. I just want to know if there is a better way of doing this :

I have an XElement object that contains about 120MB of data. The XML consists of approx 6000 elements of about 20kb each.
I am trying to call XElement.ToString() as I need to return the OuterXml in a webservice.
I am getting a System.OutOfMemoryException.
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown:

I have the same data in an XmlDocument and can call XmlDocument.OuterXml without a problem. I can also call XElement.Save() to save the XML to a file without a problem.
How can i upload a file using fileupload control from an asp.net form and store it in systems harddisk and just have a tag of that file in sql database... and also how to retirve that file for download.
I have a website that I have run for years running a custom built CMS. It has had no problems ever. I decided to create a demo (temporary url) of the CMS using the exact same website. Only people I give access to would be able to login and change it, so it basically is not in use for the most part.
I tried this demo site the past few days, and I noticed that I kept getting System.OutOfMemoryException errors. I would wait for an hour or so, then it would work. Next day, same thing.
What could explain this? 2 exact same websites....one that is used all the time (no memory issues), and one that is hardly ever used (memory issues). Doesn't really make sense to me.
We have an asp.net 2.0 application in which we get the exception of type 'System.OutOfMemoryException' whenever value is retrieved or stored in viewstate. It does not happen when we test it in local PC but when it is deployed on application server, the exception is thrown.
I am getting Error Msg Given Below..After Uploading My WebApplication..whenever i try to access my webapplication? what is the exactly reason of this Error. Some time it solved automatically when i try some time later.
Server Error in '/' Application.

I have this file upload control. I have created a folder name "images" in my visual studio project. I want to upload image into this folder. BUT, when I am uploading a image, system does not show any error. It is uploading the image. But I cannot see it into the "images" folder. But, when I browse the folder from my computer like if I go to c:/my documents/vs project/my project/images. i can see the uploaded image. Then why the image is not visible from my visual studio?? as the image is not visible in my visual studio project, user can not see the uploaded image. my code is as below:
I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. Any solutions about it??
I want this in my app:
Read DATA from Oracle Uncompress file using FileStream and BZip2
Read file uncompressed and send it to asp.net page for download. When I read file from disk, Fails !!! and get OutOfMemory.
. My Code is:
using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read)) { byte[] b2 = ReadFully(fs3, 1024); } // http://www.yoda.arachsys.com/csharp/readbinary.html public static byte[] ReadFully(Stream stream, int initialLength) { // If we've been passed an unhelpful initial length, just // use 32K. if (initialLength < 1) { initialLength = 32768; } byte[] buffer = new byte[initialLength]; int read = 0; int chunk; while ((chunk = stream.Read(buffer, read, buffer.Length - read)) > 0) { read += chunk; // If we've reached the end of our buffer, check to see if there's // any more information if (read == buffer.Length) { int nextByte = stream.ReadByte(); // End of stream? If so, we're done if (nextByte == -1) { return buffer; }
// Nope. Resize the buffer, put in the byte we've just // read, and continue byte[] newBuffer = new byte[buffer.Length * 2]; Array.Copy(buffer, newBuffer, buffer.Length); newBuffer[read] = (byte)nextByte; buffer = newBuffer; read++; } } // Buffer is now too big. Shrink it. byte[] ret = new byte[read]; Array.Copy(buffer, ret, read); return ret; }

We have the data in excel file and want to upload the same into Oracle table.To achieve this we are using following query insert into [ODBC:Driver={Microsoft ODBC for oracle};connectionstring].tablename (select * from sheet$ ) This is working fine for less records but when the record count increases following is the error faced. Error : System Resource Exceeded
We tried the following: 1. We tried to remove connection pooling for oracle. 2. We tried to remove connection pooling for excel. 3. We also verified that only one connection for each (oracle and excel) is open.
Our assumptions: 1. Either the server setting is the issue 2. Jet oledb Driver is the issue.
