If you have 100 blocks, each 4 MB large, that is not going to help you when you need one 5 MB block. If the object you are passing is is not a collection (does not implement the ICollection interface), then behind-the-scenes the List implementation is going to need to grow several (or many) Default constructor. I need to store as many random numbers as possible given available memory.

If you're sure you have enough free memory, running 64 bit OS and still getting exceptions, be sure to set this option in your project properties share|improve this answer answered Mar Don't forget that the underlying implementation of List is an array. This constructor is called by derived class constructors to initialize state in this type. I agree that your issue is probably that your dataset of 600,000 rows is probably just too large.

BTW, do not call throw e;, call throw; as otherwise your stack trace will say that the catch handler generated the exception, when actually it is the containing code. –Dominic Zukiewicz All rights reserved.

Each exception is mapped to a distinct HRESULT. Thanks once again :) Jaydip J - Thursday, February 4, 2016 11:13:07 AM Thanks a lot. Consider the "using" command when temporarily using objects that implement IDisposable. Simple as that.

If these gaps are too small for your large object, and additional space can not be requested, then you will get the System.OutOfMemoryException. Use the GetBaseException method when you want to find the root cause of an exception but do not need information about exceptions that may have occurred between the current exception and When managed code throws an exception, the runtime passes the HRESULT to the COM client.

C# Syntax: protected int HResult {get; set;} Remarks HRESULT is a 32-bit value, divided into three different fields: a severity code, a facility code, and an error code. If your users really insist on seeing that much data at once, try paging the data.

If you need to create an object which was .2GB you would not be able to do it because there is not a block large enough to fit it in and And how to change it? foreach(var number in MakeRandomNumbers(int.MaxValue)) { Console.WriteLine(number); } The above will generate as many random numbers as you wish, but only generate them as they're asked for via a foreach statement. share|improve this answer answered Mar 26 '15 at 5:55 Barry Guvenkaya 1512 add a comment| up vote 1 down vote I found turning off IntelliSense helped.

C# Syntax: public OutOfMemoryException(); Remarks This constructor initializes the Exception.Message property of the new instance to a system-supplied message that describes the error, such as "There was not enough memory This method overrides Object.ToString.Notes to inheritors: It is recommended, but not required, that ToString be overridden to return information about members declared in the derived class.

What are some reasons this could be happening? The address space is already littered with all sorts of allocated data. Why is Math.pow() (sometimes) not equal to ** in JavaScript The pros and cons of using the appearance panel to create complex shapes and strokes in AI Odd Chebyshev, part 2 This is a limitation of the .NET Framework, not just of the 32-bit address space. –Cody Gray Dec 19 '11 at 16:18 +1 For point 2.

This constructor is called by derived class constructors to initialize state in this type. I don't believe you'll need to call GC.Collect() to force a gen cycle. For example, the ArgumentException class implements ToString so that it returns the value of the ParamName property, if that value is not a null reference. The 2GB limitation means that randomNumbers must be less than 2GB.

C# Syntax: public MethodBase TargetSite {get;} Remarks If the method that throws this exception is not available and the stack trace is not a null reference (not set or Another option if you always access the values in order might be to use the overloaded constructor to specify the seed. Since most programs request working memory from the OS and do not request a file mapping, they will be limited by the system's RAM and page file size. A trace of the method calls is called a stack trace.
