运行命令。。。。进行反编译.

用记事本打开Krystalware.SlickUpload.il文件，因为我要改的是类x75979804e3328b1e的 x8da2e55498083456 ()方法，所以搜索时输入“end of method x75979804e3328b1e::x8da2e55498083456”，这样就能快速定位.

把原来的
 .method private hidebysig instance string 
  x8da2e55498083456() cil managed
  {
  // 代码大小 22 (0×16)
  .maxstack 8
  IL_0000: ldstr "<div style=\"z-index:99999;background-color:#265ecf"
  + ";border-top:1px solid #37b0e5;border-right:1px solid #37b0e5;position:a"
  + "bsolute;right:0;bottom:0;margin:0;padding:.25em .5em .25em .5em;font-si"
  + "ze:80%;background-image:url(‘http://krystalware.com/SlickUpload.ashx\?ve"
  + "rsion="
  IL_0005: ldarg.0
  IL_0006: call instance string Krystalware.SlickUpload.x75979804e3328b1e::xd82cd904f37d14cc()
  IL_000b: ldstr "’)\"><a href=\"http://krystalware.com/Products/Slick"
  + "Upload/\" style=\"color:#ffffff;text-decoration:none;\" target=\"_top\" onmo"
  + "useover=\"this.style.textDecoration=’underline’\" onmouseout=\"this.style."
  + "textDecoration=’none’\">Powered By SlickUpload Evaluation Version</a></d"
  + "iv>"
  IL_0010: call string [mscorlib]System.String::Concat(string,
  string,
  string)
  IL_0015: ret
  } // end of method x75979804e3328b1e::x8da2e55498083456

换成

.method private hidebysig instance string
x8da2e55498083456() cil managed
{
// 代码大小 11 (0xb)
.maxstack 1
.locals init (string V_0)
IL_0000: nop
IL_0001: ldstr ""
IL_0006: stloc.0
IL_0007: br.s IL_0009

IL_0009: ldloc.0
IL_000a: ret
} // end of method x75979804e3328b1e::x8da2e55498083456

重新生成所得

那dll是强命名的，所以还要生成snk文件，命令。。。。

现在是再编译的时候了，命令...

经过多次研究，生成成功，更破解后的dll文件替换原来的，OK,版权信息消失！
