Reverse Engineer .NET DLLs

Why Trust Us

If you’ve ever wanted to know how something in the .NET Framework does what it does, check out .NET Reflector. This awesome utility will reverse engineer compiled .NET dlls back into C# or VB.NET code. The example below is the reverse-engineered implementation for String.GetHashCode: 

public override unsafe int GetHashCode(){      fixed (char* text1 = ((char*) this))      {            char* chPtr1 = text1;            int num1 = 0x15051505;            int num2 = num1;            int* numPtr1 = (int*) chPtr1;            for (int num3 = this.Length; num3 > 0; num3 -= 4)            {                  num1 = (((num1 << 5) + num1) + (num1 >≫ 0x1b)) ^ numPtr1[0];                  if (num3 <= 2)                  {                        break;                  }                  num2 = (((num2 << 5) + num2) + (num2 >> 0x1b)) ^ numPtr1[1];                  numPtr1 += 2;            }            return (num1 + (num2 * 0x5d588b65));      }}
