示例1: IntroduceField
private async Task<Solution> IntroduceField(Document document, ParameterSyntax paramDecl, CancellationToken cancellationToken)
{
var rootNode = await document.GetSyntaxRootAsync();
var rewriter = new IntroduceFieldRewriter(paramDecl);
rootNode = rewriter.Visit(rootNode);
var alterConstructorRewriter = new AlterConstructorRewriter(rewriter.GeneratedField, paramDecl.FirstAncestorOrSelf<ConstructorDeclarationSyntax>(), rewriteParams: false);
rootNode = alterConstructorRewriter.Visit(rootNode);
rootNode = Formatter.Format(rootNode, document.Project.Solution.Workspace);
// Produce a new solution that has all references to that type renamed, including the declaration.
return document.WithSyntaxRoot(rootNode).Project.Solution;
}示例2: CreateFieldAsync
private async Task<Document> CreateFieldAsync(CodeRefactoringContext context, ParameterSyntax parameter,
string paramName, string fieldName, CancellationToken cancellationToken)
{
var oldConstructor = parameter.Ancestors().OfType<ConstructorDeclarationSyntax>().First();
var newConstructor = oldConstructor.WithBody(oldConstructor.Body.AddStatements(
SyntaxFactory.ExpressionStatement(
SyntaxFactory.AssignmentExpression(
SyntaxKind.SimpleAssignmentExpression,
SyntaxFactory.MemberAccessExpression(SyntaxKind.SimpleMemberAccessExpression, SyntaxFactory.ThisExpression(), SyntaxFactory.IdentifierName(fieldName)),
SyntaxFactory.IdentifierName(paramName)))));
var oldClass = parameter.FirstAncestorOrSelf<ClassDeclarationSyntax>();
var oldClassWithNewCtor = oldClass.ReplaceNode(oldConstructor, newConstructor);
var fieldDeclaration = RoslynHelpers.CreateFieldDeclaration(RoslynHelpers.GetParameterType(parameter), fieldName);
var newClass = oldClassWithNewCtor
.WithMembers(oldClassWithNewCtor.Members.Insert(0, fieldDeclaration))
.WithAdditionalAnnotations(Formatter.Annotation);
var oldRoot = await context.Document.GetSyntaxRootAsync(cancellationToken).ConfigureAwait(false);
var newRoot = oldRoot.ReplaceNode(oldClass, newClass);
return context.Document.WithSyntaxRoot(newRoot);
}示例3: Delete
private Document Delete(Document document, ParameterSyntax node)
{
var parameterList = node.FirstAncestorOrSelf<ParameterListSyntax>();
var newParameterList = parameterList.RemoveNode(node, SyntaxRemoveOptions.KeepNoTrivia);
return document.ReplaceNodeAsync(parameterList, newParameterList, CancellationToken.None)
.WaitAndGetResult_CodeModel(CancellationToken.None);
