I was reading a question about c# code optimization and one solution was to use c++ with SSE. Is it possible to do SSE directly from a c# program?

In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data (SIMD) instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in their Pentium III series of Central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!.
SSE stands for Streaming SIMD Extensions. It is essentially the floating-point equivalent of the MMX instructions. The SSE registers are 128 bits, and can be used to perform operations on a variety of data sizes and types. Unlike MMX, the SSE registers do not overlap with the floating point stack.
The GNU Compiler Collection, gcc, offers multiple ways to perform SIMD calculations.
SSE stands for Streaming SIMD Extensions. It is a set of CPU instructions dedicated to applications like signal processing, scientific computation or 3D graphics. SIMD is an acronym itself: Single Instruction, Multiple Data.
The upcoming Mono 2.2 release will have SIMD support. Miguel de Icaza blogged about the upcoming feature here, and the API is here.
Although there will be a library that will support development under Microsoft's .NET Windows runtime, it will not have the performance benefits that you are looking for unless you run the code under the Mono runtime. Which might be doable depending on your circumstances.
Update: Mono 2.2 is released
