    copied!<p>You need to get the MethodInfo. Call GetMethodBody() to get the method body structure and then call GetILAsByteArray on that. The convert that byte array into a stream of comprehensible IL. </p> <p>Roughly speaking </p> <pre><code>public static List&lt;Instruction&gt; ReadIL(MethodInfo method) { MethodBody body = method.GetMethodBody(); if (body == null) return null; var instructions = new List&lt;Instruction&gt;(); int offset = 0; byte[] il = body.GetILAsByteArray(); while (offset &lt; il.Length) { int startOffset = offset; byte opCodeByte = il[offset]; short opCodeValue = opCodeByte; // If it's an extended opcode then grab the second byte. The 0xFE // prefix codes aren't marked as prefix operators though. if (OpCodeList[opCodeValue].OpCodeType == OpCodeType.Prefix || opCodeValue == 0xFE) { opCodeValue = (short) ((opCodeValue &lt;&lt; 8) + il[offset + 1]); offset += 1; } // Move to the first byte of the argument. offset += 1; OpCode code = OpCodeList[opCodeValue]; Int64? argument = null; if (code.ArgumentSize() &gt; 0) { Int64 arg = 0; Debug.Assert(code.ArgumentSize() &lt;= 8); for (int i = 0; i &lt; code.ArgumentSize(); ++i) { Int64 v = il[offset + i]; arg += v &lt;&lt; (i*8); } argument = arg; offset += code.ArgumentSize(); } var instruction = new Instruction(startOffset, code, argument); instructions.Add(instruction); } return instructions; } </code></pre> <p>where OpCodeList is constructed via</p> <pre><code>OpCodeList = new Dictionary&lt;short, OpCode&gt;(); foreach (var opCode in typeof (OpCodes).GetFields() .Where(f =&gt; f.FieldType == typeof (OpCode)) .Select(f =&gt; (OpCode) f.GetValue(null))) { OpCodeList.Add(opCode.Value, opCode); } </code></pre> <p>You can then work out which instructions are IL property calls or member variable look ups or whatever you require and resolve then via GetType().Module.ResolveField.</p> <p>(Caveat code above more or less work but was ripped from a bigger project I did so maybe missing minor details).</p> <p><strong>Edit:</strong> Argument size is an extension method on OpCode that just uses a look up table to do find the appropriate value</p> <pre><code>public static int ArgumentSize(this OpCode opCode) { Dictionary&lt;OperandType, int&gt; operandSizes = new Dictionary&lt;OperandType, int&gt;() { {OperandType.InlineBrTarget, 4}, {OperandType.InlineField, 4}, {OperandType.InlineI, 4}, // etc., etc. }; return operandSizes[opCode.OperandType]; } </code></pre> <p>You'll find sizes in <a href="http://www.ecma-international.org/publications/standards/Ecma-335.htm" rel="nofollow noreferrer">ECMA 335</a> which you'll also need to look at for the OpCodes to find which OpCodes you to search for to find the calls you are looking for.</p>
