在Visual Studio解决scheme中更改我的所有项目的目标框架

我需要改变所有项目的目标框架。 我拥有数百个项目的许多解决scheme。

这里有什么新东西，还是我必须改变每一个项目？

Answer 1

您可以使用CodeProject上提供的Scott Dorman的Visual Studiomacros来做到这一点：

Visual Studio 2010和Target Framework版本

下面是代码，下载到您的<UserProfile>\Documents\Visual Studio 2010\Projects\VSMacros80\MyMacros文件夹，打开Visual StudiomacrosIDE（Alt-F11），并将其作为现有项目添加到“MyMacros”项目：

Answer 2

刚刚发布的Target Framework Migrator ，Visual Studio Extension，用于一次更改多个.Net项目Target Framework

Answer 3

一个PowerShell脚本，我曾经做我的。 不可否认的是，

 Get-ChildItem . -Recurse -Filter *.*proj |ForEach { $content = Get-Content $_.FullName $content |ForEach { $_.Replace("<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>", "<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>") } |Set-Content $_.FullName } 

Answer 4

总有那么简单。 一个象样的文本编辑器，如记事本+ +将包括查找/replace文件function。 只需在csproj / vbproj文件中search当前的版本string：

 <TargetFrameworkVersion>v3.5</TargetFrameworkVersion> 

并用新版本replace

 <TargetFrameworkVersion>v4.5</TargetFrameworkVersion> 

好主意虽然首先检查出来…

Answer 5

我认为到目前为止最简单的方法是使用search和replace工具。 如果它支持正则expression式是有利的。

那里肯定有不less – 我testing的第一个为我工作，但： http : //www.ecobyte.com/replacetext/

有一个说明，它在Win7上有一些问题，但我没有经历过。

该工具中的分步说明：

1. replace| 添加组| 将其命名（例如“MyGroup”）
2. 右键单击MyGroup | 添加文件…
3. select你的来源（例如使用文件夹，浏览到你想改变的项目的根文件夹）
4. 根据需要设置包含文件filter（例如* .csproj）
5. 右键单击“原始文本”下方的行 高级编辑…
6. 在search文本框中input正则expression式（例如<TargetFrameworkVersion>.*</TargetFrameworkVersion> ）
7. 在search文本下方的combobox中select“正则expression式search”
8. inputreplace文本（例如<TargetFrameworkVersion>4.0</TargetFrameworkVersion> ）
9. select目的地和备份设置（默认情况下会创build一个备份）
10. 开始replace（Ctrl + R）

现在，如果由于某种原因，你需要在代码中这样做，我也可以做到这一点（这是我如何发现这个问题）。 在这种情况下，请在评论中提出要求。

Pavel Samokha提供的Target Framework Migrator（VHQLabs）

http://visualstudiogallery.msdn.microsoft.com/47bded90-80d8-42af-bc35-4736fdd8cd13

Answer 7

从bash：

 $find . -name "*.csproj" -exec sed -b -i "s,<TargetFrameworkVersion>[^<]*</TargetFrameworkVersion>,<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>," {} \; 

Answer 8

有条件的正则expression式让我头疼。 所以这里是一个search/replace的编码解决scheme（我尽可能避免EnvDTE）。

订单对于项目文件条目似乎并不重要 ：

尝试一下：

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Text.RegularExpressions; namespace TextReplaceDemo { class Program { static void Main(string[] args) { try { ReplaceTargetFrameworkVersion("v4.0", "c:/projekt/2005", "*.csproj"); } catch (Exception ex) { Console.WriteLine(ex.Message); } } /// <summary> /// Inserts the denoted targetFramework into all occurrences of TargetFrameworkVersion. /// If the TargetFrameworkVersion is not present in the file, the method searches for the /// OutputType tag, which should be present, and inserts the TargetFrameworkVersion before that. /// </summary> /// <param name="targetFramework">New target framework (eg "v4.0")</param> /// <param name="rootDirectory">Root directory for the file search (eg "c:\Projects\2005")</param> /// <param name="fileSearchPattern">Pattern to find the project files (eg "*.csproj). /// Will get all files for empty parameter.</param> public static void ReplaceTargetFrameworkVersion(string targetFramework, string rootDirectory, string fileSearchPattern) { if (string.IsNullOrEmpty(targetFramework)) throw new ArgumentNullException("targetFramework"); if (string.IsNullOrEmpty(rootDirectory)) throw new ArgumentNullException("rootDirectory"); if (string.IsNullOrEmpty(fileSearchPattern)) fileSearchPattern = "*.*"; string regexPattern = "<TargetFrameworkVersion>.*</TargetFrameworkVersion>"; string insertText = string.Format("<TargetFrameworkVersion>{0}</TargetFrameworkVersion>", targetFramework); string alternativeMarker = "<OutputType>"; // get all files List<FileInfo> files = GetAllFiles(rootDirectory, fileSearchPattern); // iterate over found files foreach (var file in files) { string fileContent = File.ReadAllText(file.FullName); Match match = Regex.Match(fileContent, regexPattern); string newfileContent = null; if (match.Success) { // replace <TargetFrameworkVersion> newfileContent = fileContent.Replace(match.Value, insertText); } else if (fileContent.Contains(alternativeMarker)) { // create <TargetFrameworkVersion> newfileContent = fileContent.Replace(alternativeMarker, insertText + Environment.NewLine + " " + alternativeMarker); } // overwrite file if (newfileContent != null) File.WriteAllText(file.FullName, newfileContent); } } /// <summary> /// Recursive function to find all files in a directory by a searchPattern /// </summary> /// <param name="path">Path to the root directory</param> /// <param name="searchPattern">Pattern for the file search, eg "*.txt"</param> public static List<FileInfo> GetAllFiles(string path, string searchPattern) { List<FileInfo> files = new List<FileInfo>(); DirectoryInfo dir = new DirectoryInfo(path); if (dir.Exists) { // get all files in directory files.AddRange(dir.GetFiles(searchPattern)); // get all files of subdirectories foreach (var subDir in dir.GetDirectories()) { files.AddRange(GetAllFiles(subDir.FullName, searchPattern)); } } return files; } } } 

Answer 9

您可以使用macros来做到这一点，或记住，VS项目文件是文本文件，这意味着一个简单的全局search和replace可以实现相同的，是一个更一般的技术，使大量的项目文件相同的变化。

首先备份现有的项目文件，然后进行所需的更改（例如更改目标框架）。 使用WinDiff或WinMerge将新的项目文件与备份进行比较。 这将告诉你你需要做的改变。 然后使用Visual Studio IDE的“在文件中查找和replace”function对所有项目文件进行更改。
