使用roslyn api獲取所有類型的擴展方法

Question

我想獲得類型的所有擴展方法。例如，對於類型string，如果我使用semanticmodel方法lookupsymbols。

var sourceText = @"string a = ""; 
a." 
var tree= CSharpSyntaxTree.ParseText(sourceTextx...); 
.... 
var members = semanticModel.LookupSymbols(source.IndexOf("a."), someType, includeReducedExtensionMethods: true); 
//this return all members with extension methods for type string someExtMethod(this string text).... 


//I want get all extension with methods where first param might be one of them 
var interfaces = someType.AllInerfaces; 
//for example IEnumerable<out T>, methods like: Select, Where, Aggregate... 

Answer 1

致電SemanticModel.LookupSymbols將所有有效符號從容器中取出。

這是how IntelliSense works。
