Question

我想要一个能够写入文件的程序：

addr_new = serverInfo.REGION_DICT[0][serverNum]["channel"][serverChannel]["ip"]

，但必须忽略文本中的字符“”

我的结果：Visual Studio不会忽略字符串中的字符“”并且需要像IP等字符串。请求帮助

谢谢我的英语

有我的计划：

 string path = System.IO.Directory.GetCurrentDirectory()+ "logininfo.py";

    string[] lines = {
    "import serverInfo"
    , "serverNum=1"
    , "serverChannel=1"
    , "addr_new = serverInfo.REGION_DICT[0][serverNum]["channel"][serverChannel]["ip"]"};

System.IO.StreamWriter file = new System.IO.StreamWriter(path);
file.WriteLine(lines);

file.Close();

我差点忘了我想要更多行，这个程序被修剪

Answer 1

您可以使用斜杠转义这些字符：

string[] lines = {
    " import serverInfo" ,
    "serverNum=1" ,
    "serverChannel=1" ,
    "addr_new = serverInfo.REGION_DICT[0][serverNum][\"channel\"][serverChannel][\"ip\"] "};

或使用@-quoted string并使用""代替"，如下所示：

string[] lines = {
    " import serverInfo" ,
    "serverNum=1" ,
    "serverChannel=1" ,
    @"addr_new = serverInfo.REGION_DICT[0][serverNum][""channel""][serverChannel][""ip""] "};

Answer 2

您需要concatenate字符串：

"addr_new = serverInfo.REGION_DICT[0][serverNum][" + channel + "][serverChannel][" + ip + "]"};

或者，如果您希望将“channel”用作字符串值，请使用单引号：

"addr_new = serverInfo.REGION_DICT[0][serverNum]['channel'][serverChannel]['ip']"};

Answer 3

转义特殊字符

"addr_new = serverInfo.REGION_DICT[0][serverNum][\"channel\"][serverChannel][\"ip\"]"

忽略字符串中的字符“”
