Question

我正在使用NSIS为c＃中的桌面应用程序创建exe，我必须为用户将少量文件写入AppData Roaming文件夹

我尝试了以下代码

 !define ROAMING_FOLDER_ROOT "$APPDATA\APPDUMMY\APPFILES"
 MessageBox MB_OK 'AppDATA FOLDER "${ROAMING_FOLDER_ROOT}"'  #here i am getting the correct path of the Appdata roaming folder frm variable
Section -Additional
SetOutPath "$ROAMING_FOLDER_ROOT"
SetOverwrite off 
File "C:\MYAPPSOURCECODE\BIN\BookStore.sqlite"
SetOverwrite ifnewer
File "C:\MYAPPSOURCECODE\BIN\AppSettings.xml"
File "C:\MYAPPSOURCECODE\BIN\Resources\defData.xml"
File "C:\MYAPPSOURCECODE\BIN\Resources\dummy.html"
SetOutPath "$ROAMING_FOLDER_ROOT\Resources"
File "C:\MYAPPSOURCECODE\BIN\Resources\appjsfile.js"
SectionEnd

虽然我正在尝试使用$ LocalAppData对AppDAta Local文件夹进行写入，但我想让它可写入漫游文件夹

Answer 1

啊，似乎，您正在使用常见的shell上下文尝试设置

SetShellVarContext current

在获得$ APPDATA之前

。

 Var ROAMING_FOLDER_ROOT 
 MessageBox MB_OK 'AppDATA FOLDER "${ROAMING_FOLDER_ROOT}"'  #here i am getting the correct path of the Appdata roaming folder frm variable
Section -Additional
SetShellVarContext current
StrCpy $ROAMING_FOLDER_ROOT "$APPDATA\APPDUMMY\APPFILES"
SetOutPath "$ROAMING_FOLDER_ROOT"
SetOverwrite off 
File "C:\MYAPPSOURCECODE\Models\BookStore.sqlite"
SetOverwrite ifnewer
File "C:\MYAPPSOURCECODE\BIN\AppSettings.xml"
File "C:\MYAPPSOURCECODE\BIN\Resources\defData.xml"
File "C:\MYAPPSOURCECODE\BIN\Resources\dummy.html"
SetOutPath "$ROAMING_FOLDER_ROOT\Resources"
File "C:\MYAPPSOURCECODE\BIN\Resources\appjsfile.js"
SectionEnd

如果您查看发布的代码，可以在${ROAMING_FOLDER_ROOT}调用中看到您引用SetOutPath定义，但在调用$ROAMING_FOLDER_ROOT时，您引用了一个名为${}的变量这可能会产生编译器警告。访问定义时，请确保使用SetShellVarContext current ; Current is the default DetailPrint AppData=$AppData ; C:\Users\%username%\AppData\Roaming SetShellVarContext all DetailPrint AppData=$AppData ; C:\ProgramData (This is in the All Users folder on XP) SetShellVarContext current ; Restore it back to the default语法！

NSIS有一个名为shell上下文的概念，$ AppData常量受此影响：

使用NSIS脚本将文件写入Roaming文件夹
