解决方案
解决方案二：
C++的代码:GPSSUPPORT_APIint__stdcallZlibUncompress(unsignedchar*compr,unsignedlongcomprLen,unsignedchar**uncompr,unsignedlong*uncomprLen);
解决方案三：
C++代码写错了.是这样的:GPSSUPPORT_APIint__stdcallZlibUncompress(unsignedchar*compr,unsignedlongcomprLen,unsignedchar**uncompr,unsignedlong*uncomprLen);
解决方案四：
看不出来，不过char*一般对应C#里的string或者StringBuilder
解决方案五：
先用C写个测试程序看看，

[DllImport("xx.dll")]publicstaticexternintZlibUncompress(byte[]compr,uintcomprLen,refbyte[]uncompr,refuintuncomprLen);
解决方案八：
[DllImport("xx.dll")]publicstaticexternintZlibUncompress(byte[]compr,uintcomprLen,refbyte[]uncompr,refuintuncomprLen);privatebyte[]Keys={0x78,0xDA,0x63,0x60,0x60,0x6C,0x60,0x6A,0x63,0x64,0x60,0x16,0x06,0x00,0x06,0x59,0x01,0x21};uintblen=0;uintalen=Convert.ToUInt32(Keys.Length);byte[]buffer=newbyte[128];intErr=XWAPI.ZlibUncompress(Keys,alen,refbuffer,refblen);我这样写了.可是blen是对的.但buffer的没值,值不对.请上楼的朋友帮我看看.谢谢.
解决方案九：
LZ的c++函数是否写错了?我在网上查了一下LZ用的是zlib.dll来压缩解压缩吧貌似c++的函数原型不是这样的你再仔细检查检查压缩解压缩的别写反了..
解决方案十：
[DllImport("xx.dll")]publicstaticexternintZlibUncompress(byte[]compr,uintcomprLen,refbyte[]uncompr,refuintuncomprLen);
解决方案十一：
[DllImport("xx.dll")]publicstaticexternintZlibUncompress(byte[]compr,uintcomprLen,refbyte[]uncompr,refuintuncomprLen);
