Question

我有以下PowerShell-Command，直接从powershell调用时效果很好：

Get-ChildItem -r -include 'AssemblyInfo.cs' `
| foreach-object { $a = $_.fullname; ( get-content $a ) `
| foreach-object { $_ -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', '$1[assembly:AssemblyInformationalVersion("$3-alpha")]' } ` 
| Out-File $_.fullname }

但是，当从cmd调用时（我们的Buildservers-Process在cmd中运行）它不会引发错误但它也不会按预期替换字符串（它可以从任何cmd窗口重现）：

PowerShell -Command "(Get-ChildItem -r -include  'AssemblyInfo.cs') | foreach-object { $a = $_.fullname; ( get-content $a ) | foreach-object { $_ -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', '$1[assembly:AssemblyInformationalVersion("$3-alpha")]' } | Out-File $_.fullname }"

我尝试使用and＆amp;`来转义引号和命令，但它没有帮助。

我错过了什么？

命令字符串中有双引号：

... -replace '((\[assembly:\sAssemblyVersion\(")(\d\.\d\.\d\.\d)("\)\]))', ...
                                              ^                  ^

必须为CMD转义这些内容：

... -replace '((\[assembly:\sAssemblyVersion\(\")(\d\.\d\.\d\.\d)(\"\)\]))', ...
                                              ^^                  ^^

从cmd调用时，字符串替换不起作用
