.NET Obfuscation and Intellectual Property
By Brent Rector, August 01, 2002
Protecting the intellectual property in your compiled app from reverse engineering is a concern regardless of what language you use, but the metadata in .NET code increases its susceptibility to reverse engineering. Obfuscation can help thwart such attempts. Brent explores the benefits of several obfuscation strategies.

Example 2: IL Decompilation of GetNewName
private string GetNewString(string currentString, int requiredLength) {
int local0;
requiredLength = requiredLength + 1;
if (requiredLength > this.m_MaxCapacity)
throw new ArgumentOutOfRangeException( Environment.GetResourceString
("ArgumentOutOfRange_NegativeCapacity"), "requiredLength");
local0 = currentString.Capacity * 2;
if (local0 < requiredLength)
local0 = requiredLength;
if (local0 > this.m_MaxCapacity)
local0 = this.m_MaxCapacity;
if (local0 <= 0)
throw new ArgumentOutOfRangeException( Environment.GetResourceString
("ArgumentOutOfRange_NegativeCapacity"));
return String.GetStringForStringBuilder(currentString, local0);
})
