fm.OpenMap(); fm.GetZDLH_dll(); fm.GetZDHZ_dll(); string JL_dir = Global.gv_AppPath + "C170701" + "\\" + "C170701"; // rst = open_jl(JL_dir); fm.rst = fm.Openjl(JL_dir); fm.JLJS_DLL(); 目测是这部分代码造成的。

引用 1 楼 duanzi_peng 的回复:

fm.OpenMap(); fm.GetZDLH_dll(); fm.GetZDHZ_dll(); string JL_dir = Global.gv_AppPath + "C170701" + "\\" + "C170701"; // rst = open_jl(JL_dir); fm.rst = fm.Openjl(JL_dir); fm.JLJS_DLL(); 目测是这部分代码造成的。

如果实在无法发现源头，可以把数据库和文件操作尝试改成using写法

是不是调用的动态链接库dll里边会有内存泄漏的问题呢！
