使用 Roslyn 创建方法调用分析器 [英] Create a method call analyzer with Roslyn

问题描述

我需要解析 .cs 文件以查找特定方法.例如，一旦调用了名为X"的方法，分析器就应该检测到它.

I need to parse a .cs file to look for a particular method. For instance, once the method named "X" is called, the analyzer should detect it.

如何检测这个特定节点是一个方法?

How can detect that this particular node is a method?

推荐答案

如果你有一个语法节点和语义模型，你可以试试这个:

If you have a syntax node and semantic model for it you can try this:

// node – is your current syntax node
// semanticalModel – is your semantical model
ISymbol symbol = semanticModel.GetSymbolInfo(node).Symbol ?? semanticModel.GetDeclaredSymbol(node);
if(symbol.Kind == SymbolKind.Method)
{
    // methodName – is a method's name that you are looking
    if((symbol as IMethodSymbol).Name == methodName)
    {
        // you find your method
    }
}

另外，不使用语义模型也可以确定当前语法节点是你的方法，但比上面的方法要难一些

Also, you can determine that the current syntax node is your method without using the semantic model but it's a little harder than the way is above
