獲取引用方法的程序集名稱

Question

在Roslyn中使用SemanticModel是否可以獲取引用方法的程序集名稱？

var refMethod = string.Empty;
var refClass = string.Empty;
var refDocument = string.Empty;
if (location.Document.TryGetSemanticModel(out var referenceSemanticModel))
{
    var enclosingSymbol = referenceSemanticModel.GetEnclosingSymbol(location.Location.SourceSpan.Start);
if (!(enclosingSymbol is null))
{                                                        
refMethod = enclosingSymbol.Name;
refClass = enclosingSymbol.ContainingType.Name;
refDocument = Path.GetFileName(location.Location.SourceTree.FilePath);

Answer 1

就在這里。 我猜這兩行應該在您的代碼中起作用：

var containingAssembly = enclosingSymbol.ContainingAssembly;
var containingAssemblyName = containingAssembly.Name;

ContainingAssembly具有程序集名稱，位置等信息。 您可以放置​​一個斷點並檢查它。

如果不起作用，下面是我出於相同目的使用的代碼，效果很好：

private void AnalyzeNode(SyntaxNodeAnalysisContext context)
{
    var invocationExpr = (InvocationExpressionSyntax)context.Node;
    var memberAccessExpr = invocationExpr.Expression as MemberAccessExpressionSyntax;
    var memberSymbol = context.SemanticModel.GetSymbolInfo(memberAccessExpr).Symbol as IMethodSymbol;
    var namespace= memberSymbol?.ContainingNamespace;
    var assemblyName = memberSymbol?.ContainingAssembly;
}
