FlyTreeView for ASP.NET 3.1 破解手記

這裡的DateTime(2004, 7, 11)就是控制項的到期時間。說來簡單，其實要找到它還是費了一番周折的。根據上面的線索，我在用ildasm工具反組譯碼出的NineRays.Web.UI.WebControls.FlyTreeView.IL檔案中找到了對應的IL代碼如下：
.method private hidebysig specialname rtspecialname static
void .cctor() cil managed
{
// 代碼大小 19 (0x13)
.maxstack 4
IL_0000: ldsflda valuetype [mscorlib]System.DateTime Global::TRIAL_EXPIRE_DATE
IL_0005: ldc.i4 0x7d4
IL_000a: ldc.i4.7
IL_000b: ldc.i4.s 11
IL_000d: call instance void [mscorlib]System.DateTime::.ctor(int32, int32,int32)
IL_0012: ret
} // end of method Global::.cctor
代碼中的0x7d4 便是十六進位的年號2004，我不想太貪，就把它改成2050年吧，十六進位是0x802F
.method private hidebysig specialname rtspecialname static
void .cctor() cil managed
{
// 代碼大小 19 (0x13)
.maxstack 4
IL_0000: ldsflda valuetype [mscorlib]System.DateTime Global::TRIAL_EXPIRE_DATE
IL_0005: ldc.i4 0x802F
IL_000a: ldc.i4.7
IL_000b: ldc.i4.s 11
IL_000d: call instance void [mscorlib]System.DateTime::.ctor(int32, int32,int32)
IL_0012: ret
} // end of method Global::.cctor
儲存前別忘了刪除IL代碼起始部分類似下面的代碼
.publickey =(00 24 00 00 04 80 00 00 94 00 00 00 06 02 00 00 // .$..............
00 24 00 00 52 53 41 31 00 04 00 00 01 00 01 00 // .$..RSA1........
