今天看一篇文章講述怎么在net環境下使用com組件中的IL修改的代碼中看到了
Marshal（[+1])?? 這樣一個東東，查了不少資料，但是仍然一無所獲，請問這個東東做什么用的？其中的“+1”是指示什么？這個數字到底指向什么？
引用原文：
.method public hidebysig newslot virtual abstract ?????????? instance void? MyNextLongs([in] int32 nReq,???????????????????????????????? // Replace this: [out] int32& rgelt,???????????????????????????????? // With this:???????????????????????????????? [out] int32[] marshal([ + 1]) rgelt,???????????????????????????????? [out] int32& pnFetched) runtime managed internalcall

就是 陣列的意思
MICROSOFT提交給標準化組織ECMA的規范
可以參考
ECMA-334 --定義了C#編程語言的語法和語義
ECMA-335--定義了許多.NET平臺的細節,統稱CIL.
?
[Example:
.method int32 M1( int32 marshal(int32), bool[] marshal(bool[5]) )
Method M1 takes two arguments: an int32, and an array of 5 bools.
.method int32 M2( int32 marshal(int32), bool[] marshal(bool[+1]) )
Method M2 takes two arguments: an int32, and an array of bools: the number of elements in that array is
given by the value of the first parameter.
.method int32 M3( int32 marshal(int32), bool[] marshal(bool[7+1]) )
Method M3 takes two arguments: an int32, and an array of bools: the number of elements in that array is
given as 7 plus the value of the first parameter. end example]
