http://blogs.msdn.com/clrcodegeneration/archive/2008/02/08/performance-implications-of-unmanaged-array-accesses.aspxI was recently shown the following code and asked why the loop calling SafeAccess executed significantly faster than the second loop calling UnsafeAccess : static int [] intarray = new int [ 5000 ]; static void SafeAccess(int a, int b) { int temp = intarray[a];en-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/clrcodegeneration/archive/2008/02/08/performance-implications-of-unmanaged-array-accesses.aspx#7558353Sat, 09 Feb 2008 12:55:31 GMT91d46819-8472-40ad-a661-2c78acb4018c:7558353jvangael<p>Is there a good resource to learn when it would be appropriate to use unsafe accesses? I can imagine that if there were a loop in the unsafe method, and the problem were large enough, the range checking would incur a performance overhead?</p> <p>Any place or book I could check out to learn more?</p> <p>Jurgen</p>
