經(jīng)過幾天的實(shí)驗(yàn)，問題已解決，現(xiàn)在向客戶報(bào)告：
C#使用C++編譯的動(dòng)態(tài)鏈接庫的時(shí)候，入口點(diǎn)名稱發(fā)生了變化，請(qǐng)參見如下代碼：
const int ISA_P1 = 1;
const int ISA_P2 = 2;
const int ISA_P3 = 3;
const int ISA_P4 = 4;
const int ISA_P5 = 5;
const int ISA_CS0n = 0;
const int ISA_CS1n = 1;
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?InitEM9000ISA@@YAHXZ")]
public static extern int InitEM9000ISA();
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?Swap2DIO@@YAHH@Z")]
public static extern int Swap2DIO(int Port);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?Swap2ISA@@YAHH@Z")]
public static extern int Swap2ISA(int Port);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?EM9000_WRITE@@YAHHIE@Z")]
public static extern int EM9000_WRITE(int nSeg, uint nOffset, byte Value);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?EM9000_READ@@YAEHI@Z")]
public static extern byte EM9000_READ(int nSeg, uint nOffset);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?SetPortDir@@YAHHH@Z")]
public static extern int SetPortDir(int Port, int Mode);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?GetPortState@@YAHH@Z")]
public static extern int GetPortState(int Port);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?EM9000_INB@@YAEH@Z")]
public static extern byte EM9000_INB(int Port);
[DllImport("EM9000_ISA_DLL.dll", EntryPoint = "?EM9000_OUTB@@YAHHE@Z")]
public static extern int EM9000_OUTB(int Port, byte Value);
