通过xml方式更改项目文件的元素(changing an element of project file by xml means)

有时我必须将最多60个winforms或类库项目加载到解决方案中..并更改每个项目的输出路径和参考路径。

所以我为此写了一个wpf应用程序

private void Button_Click(object sender, RoutedEventArgs e) { var path = txtRootPath.Text; var projFiles = System.IO.Directory.GetFiles(path, "*.csproj", SearchOption.AllDirectories); foreach (var item in projFiles) { var xDoc = XDocument.Load(item); var outputNodes = xDoc.Root.Descendants("OutputPath"); foreach (var outoutNode in outputNodes) { //this part is never hit.. outoutNode.Value = txtOutputPath.Text; } //similarly for referencePath } lblResult.Content = string.Format("Files: {0}", projFiles.Count()); }

但是outputNodes集合将为空

有人可以告诉我这里做错了什么

编辑：

我发现问题在于Project元素中的xmlns="http://schemas.microsoft.com/developer/msbuild/2003"属性。

解：

如此解决方案中给出的 - 将Visual Studio项目文件解析为XML 具有XDocument命名空间问题的Linq-to-XML

some times I will have to load up to 60 winforms or class library projects into a solution.. and change the output path and reference path for each of them..

so I wrote a wpf application for the same

private void Button_Click(object sender, RoutedEventArgs e) { var path = txtRootPath.Text; var projFiles = System.IO.Directory.GetFiles(path, "*.csproj", SearchOption.AllDirectories); foreach (var item in projFiles) { var xDoc = XDocument.Load(item); var outputNodes = xDoc.Root.Descendants("OutputPath"); foreach (var outoutNode in outputNodes) { //this part is never hit.. outoutNode.Value = txtOutputPath.Text; } //similarly for referencePath } lblResult.Content = string.Format("Files: {0}", projFiles.Count()); }

but outputNodes collection will be empty

could somebody please tell what am I doing wrong here

EDIT:

I figured out that the problem is with xmlns="http://schemas.microsoft.com/developer/msbuild/2003" attribute in Project element..

Solution:

as given in this solution - Parsing Visual Studio Project File as XML Linq-to-XML with XDocument namespace issue
