问题描述
在编译项目时，我会提示以下警告:
警告1至少'CorRuntimeHost.SwitchOutLogicalThreadState'的参数之一不能被运行时封送处理程序封送处理.因此，此类参数将作为指针传递，并且可能需要不安全的代码进行操作.
警告2至少'ICorRuntimeHost.SwitchOutLogicalThreadState'的参数之一不能被运行时封送处理程序封送处理.因此，此类参数将作为指针传递，并且可能需要不安全的代码进行操作.
警告3类型库导入程序无法转换成员'tag_VerError.item1_data'的签名.
警告4 ;类型库导入程序无法转换成员'tag_VerError.item2_data'的签名.
我直接在项目中引用的标准库是:

When compiling my project I egt the following warnings:
Warning 1 At least one of the arguments for 'CorRuntimeHost.SwitchOutLogicalThreadState' cannot be marshaled by the runtime marshaler. Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate.
Warning 2 At least one of the arguments for 'ICorRuntimeHost.SwitchOutLogicalThreadState' cannot be marshaled by the runtime marshaler. Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate.
Warning 3 The type library importer could not convert the signature for the member 'tag_VerError.item1_data'.
Warning 4 The type library importer could not convert the signature for the member 'tag_VerError.item2_data'.
Standard libraries I refference directly in my project are:

推荐答案
警告1& 2几乎说系统不知道如何编组参数 这些函数，所以它将只传递一个指针.当函数采用系统编组部分不知道的参数时，可能会发生这种情况.我想这意味着它更不安全，因为您不知道另一个 结束将与指针有关，但如果它起作用，则可以忽略该消息.
The warning 1 & 2 is pretty much saying that the system doesn't know how to marshal the parameters to those functions, so it will just pass a pointer. This probably happens when the functions take a parameter that the marshalling part of the system doesn't know about. I guess this means that it is a bit more unsafe, in that you don't know what the other end is going to do with the pointer, but if it works, its probably OK to ignore the message.
