我有一个msbuild文件，一个部分在一个文件中做了一堆文本替换（生成一个填写模板nuspec文件）
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Version$" ReplacementText="$(Version)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$SolutionName$" ReplacementText="$(SolutionName)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Authors$" ReplacementText="$(Authors)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Owners$" ReplacementText="$(Owners)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Summary$" ReplacementText="$(Summary)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Description$" ReplacementText="$(Description)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$Tags$" ReplacementText="$(Tags)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$ProjectUrl$" ReplacementText="$(ProjectUrl)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$IconUrl$" ReplacementText="$(IconUrl)" />
<ReplaceFileText InputFilename="$(SolutionDir)$(SolutionName).nuspec"
MatchExpression="$BuildDir$" ReplacementText="$(BuildDir)" />
如您所见，除了要替换的实际文本和属性名称（它们本身是相同的）之外，这是大量的重复。
有没有办法重写它？ 我没有太多运气找到正确的命令。
替换文件文本是一个自定义任务。
我们可以将混合复杂化为"如果我想对不仅仅是那个 .nuspec 文件进行这些更改怎么办？"，但您正在尝试重构它以使其可读。
让我们创建一个我们称之为"batching.proj"的示例项目，我们可以使用 "MsBuild.exe Batching.proj" 从命令行调用该项目并查看输出。
