ComponentArt 2009.3 破解

这里就使用了License, LicenseProvider, RegistryFileLicenseProvider。直接删除

public virtual bool IsLicensed()
{
    if (this.License != null)
    {
        return true;
    }
    try
    {
        this.License = LicenseManager.Validate(base.GetType(), this);
        return true;
    }
    catch
    {
        return false;
    }
}

使他返回TRUE；

换成：

.method public hidebysig newslot virtual instance bool IsLicensed() cil managed
{
    .maxstack 1
    .locals init (
        [0] bool CS$1$0000)
    L_0000: nop
    L_0001: ldc.i4.1
    L_0002: stloc.0
    L_0003: br.s L_0005
    L_0005: ldloc.0
    L_0006: ret
}

2. 删除VS2005对项目的权限检查。
一般就是依赖了LicenseProviderAttribute，打开IL，找到类似的代码，直接删除。20 多个！

 .custom instance void [System]System.ComponentModel.LicenseProviderAttribute::.ctor(class

[mscorlib]System.Type) = ( 01 00 3C 43 6F 6D 70 6F 6E 65 6E 74 41 72 74 2E   // ..<ComponentArt.
                                                                                                                       4C 69 63 65 6E 73

69 6E 67 2E 50 72 6F 76 69 64   // Licensing.Provid
                                                                                                                       65 72 73 2E 52 65
