Roslyn CodeFix Provider (VS2015)：如何获取类属性/字段类型

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;

// 获取类属性/字段类型的方法
public static string GetPropertyOrFieldType(string code, string propertyName)
{
    SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);
    CompilationUnitSyntax root = syntaxTree.GetCompilationUnitRoot();

    // 查找属性或字段声明
    var propertyOrField = root.DescendantNodes().OfType<PropertyDeclarationSyntax>()
        .FirstOrDefault(p => p.Identifier.ValueText == propertyName)
        ?? root.DescendantNodes().OfType<FieldDeclarationSyntax>()
        .FirstOrDefault(f => f.Declaration.Variables.Any(v => v.Identifier.ValueText == propertyName));

    // 获取属性或字段的类型
    if (propertyOrField != null)
    {
        return propertyOrField.Type.ToString();
    }

    return null;
}

string code = @"
public class MyClass
{
    public string MyProperty { get; set; }
    public int MyField;
}";

string propertyName = "MyProperty";
string propertyType = GetPropertyOrFieldType(code, propertyName);

Console.WriteLine($"The type of {propertyName} is {propertyType}.");
