如何从泛型类型自动设置字段？

public static void SetField<T>(T obj, string fieldName, object value)
{
    Type type = typeof(T);
    PropertyInfo propertyInfo = type.GetProperty(fieldName);
    if (propertyInfo != null && propertyInfo.CanWrite)
    {
        propertyInfo.SetValue(obj, value);
    }
}

public class MyClass
{
    public string MyField { get; set; }
}

MyClass myObj = new MyClass();
SetField(myObj, "MyField", "Hello World");
Console.WriteLine(myObj.MyField);  // 输出：Hello World
