将多个更改应用于roslyn中的解决方案 [英] Applying multiple changes to a solution in roslyn
本文介绍了将多个更改应用于roslyn中的解决方案的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想将更改应用于解决方案的多个文档,但仅反映出第一个更改,其余的则被拒绝。此链接显示了仅一次将更改应用于解决方案的情况。解决该问题的方法是什么。我将不胜感激指向解决方案或代码段的链接。
I want to apply changes to several documents of a solution but only the first change is reflected and rest of them are rejected.This link shows how only once can changes be applied to a solution. What would be a work around for this. I would appreciate a link directing to a solution or a code snippet.
这是我的功能:
public static async Task<bool> AddMethod(string solutionPath)
{
var workspace = MSBuildWorkspace.Create();
var solution = await workspace.OpenSolutionAsync(solutionPath);
ClassDeclarationSyntax cls = SyntaxFactory.ClassDeclaration("someclass");
foreach (var project in solution.Projects)
{
foreach(var document in project.Documents)
{
Document doc = project.GetDocument(document.Id);
var root = await doc.GetSyntaxRootAsync();
var classes = root.DescendantNodes().Where(n => n.IsKind(SyntaxKind.ClassDeclaration));
if (classes.Count() != 0)
{
SyntaxNode FirstClass = classes.First() as ClassDeclarationSyntax;
if (FirstClass != null)
{
var newRoot = root.ReplaceNode(FirstClass, cls);
doc = doc.WithText(newRoot.GetText());
Project proj = doc.Project;
var abc = workspace.TryApplyChanges(proj.Solution);
}
}
}
}
return true;
}
推荐答案
解决方法是使用 ProjectId
和 DocumentId
并一次将所有更改应用于工作区。
The workaround is to use ProjectId
and DocumentId
and apply all your changes to the workspace at one time.
尝试以下操作:
public static async Task<bool> AddMethod(string solutionPath)
{
var workspace = MSBuildWorkspace.Create();
var solution = await workspace.OpenSolutionAsync(solutionPath);
ClassDeclarationSyntax cls = SyntaxFactory.ClassDeclaration("someclass");
foreach (var projectId in solution.ProjectIds)
{
var project = solution.GetProject(projectId);
foreach (var documentId in project.DocumentIds)
{
Document doc = project.GetDocument(documentId);
var root = await doc.GetSyntaxRootAsync();
var firstClass = root.DescendantNodes().OfType<ClassDeclarationSyntax>().FirstOrDefault();
if (firstClass == null)
return true;
var newRoot = root.ReplaceNode(firstClass, cls);
doc = doc.WithText(newRoot.GetText());
//Persist your changes to the current project
project = doc.Project;
}
//Persist the project changes to the current solution
solution = project.Solution;
}
//Finally, apply all your changes to the workspace at once.
var abc = workspace.TryApplyChanges(solution);
return true;
}
