<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">如果想得到一个可由</span><span lang="EN-US">.NET</span><span style="FONT-FAMILY: 宋体">运行库加载的非可执行文件</span><span lang="EN-US">(</span><span style="FONT-FAMILY: 宋体">例如</span><span lang="EN-US">DLL)</span><span style="FONT-FAMILY: 宋体">，就必须把它编译为一个库。如果把</span><span lang="EN-US">C#</span><span style="FONT-FAMILY: 宋体">文件编译为一个模块，就不会创建任何程序集。虽然模块不能由运行库加载，但可以使用</span><span lang="EN-US">/addmodule</span><span style="FONT-FAMILY: 宋体">选项编译为另一个清单。</span></p>
<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">另一个需要注意的选项是</span><span lang="EN-US">/out</span><span style="FONT-FAMILY: 宋体">，该选项允许用户指定由编译器生成的输出文件名。如果没有指定</span><span lang="EN-US">/out</span><span style="FONT-FAMILY: 宋体">选项，编译器就会使用输入的</span><span lang="EN-US">C#</span><span style="FONT-FAMILY: 宋体">文件名，加上根据目标类型的扩展名来建立输出文件名</span><span lang="EN-US">(</span><span style="FONT-FAMILY: 宋体">例如</span><span lang="EN-US">.exe</span><span style="FONT-FAMILY: 宋体">表示</span><span lang="EN-US">Windows</span><span style="FONT-FAMILY: 宋体">或控制台应用程序，</span><span lang="EN-US">.dll</span><span style="FONT-FAMILY: 宋体">表示类库</span><span lang="EN-US">)</span><span style="FONT-FAMILY: 宋体">。注意</span><span lang="EN-US">/out</span><span style="FONT-FAMILY: 宋体">和</span><span lang="EN-US">/t(</span><span style="FONT-FAMILY: 宋体">或</span><span lang="EN-US">/target)</span><span style="FONT-FAMILY: 宋体">选项必须放在要编译的文件名前面。</span></p>
