是否有任何文档或是否有我可以参考的cecil源代码的一部分，以全面了解cecil将用于给定Operand值的Code类型？例如：我可以从MethodBodyRocks收集Ldloc Operand VariableDefinition类型{{1}}，但我无法通过其他一些指令来追踪这一点码。

要添加到poupou的答案，OpCodes.cs会显示为每个指令代码分配的OperandType。使用此OperandType，您可以查看CodeReader.ReadOperand，了解这些OperandType如何用于确定构造哪种具体对象类型。另请注意，CodeReader.ReadCode在返回之前使用CodeReader.ResolveBranches将一些操作数从指令偏移转换为Instruction个对象。
我创建了这个表，每次挖掘源代码都非常方便（此表中未涵盖的内容应该包含InlineNone OperandType）：

您可以查看OpCodes.cs文件中每个OpCode的定义。
E.g。对于 Ldloc ，您会看到 OperandType.InlineVar
