Question

我想编写一个批处理文件来查找所有.vsdm文件，文件名必须包含子字符串＆＃34; 2.4＆＃34;。但是我的代码告诉我所有的.vsdm文件都包含子字符串＆＃34; 2.4＆＃34;这是不正确的。

FOR /R %completepath% %%G IN (*.vsdm) DO (
set file=%%~nG

If not "%file%"=="%file:2.4=%" (
    echo Filename contains 2.4
) else (
    echo Filename does NOT contains 2.4
)
)

谁能告诉我哪里弄错了？谢谢

Answer 1

if(userChoice.defeats(computerChoice)){
    //handle user win here
}else if(computerChoice.defeats(userChoice){
   //handle computer win here
}else{
   //handle tie here
}

在If "%file%"=="%file:2.4=%" ( echo Filename "%file%" does NOT contain 2.4 ) else ( echo Filename "%file%" contains 2.4 )中包含文件名可能会显示更多信息。我认为双重否定方法没有理由。代码操作的方式可能取决于指令在代码中的精确位置，例如，如果这些行包含在任何类型的循环或代码块中，则操作可能取决于其他元素，因此它很重要上下文中的代码，以及预期和实际发生的内容的示例。

有一两篇关于echo的SO文章，OP应该熟悉这些文章。

您可以使用 Where /? 命令，使用通配符（？*）和UNC路径。
