错误    1    “ddr.route”并不包含“dirtance”的定义    C:\Documents and Settings\user\My Documents\Visual Studio 2005\Projects\lianxi\lianxi\Program.cs    36    21    lianxi


错误    2    “ddr.route”并不包含“dirtance”的定义    C:\Documents and Settings\user\My Documents\Visual Studio 2005\Projects\lianxi\lianxi\Program.cs    38    25    lianxi


请问这里要怎么修改呀
