带有嵌套属性的c#反射

Question

试图使用反射设置嵌套属性的值两层，但我得到一个对象并不不是目标对象错误。类型化的对象看起来像这样:project.EnvironmentalAessment.SomeDocument.Review

var _review = new Review() { .... };
var docProp = project.EnvironmentalAssessment.GetType().GetProperty(techStudy.DocumentProperty);
    var docType = docProp.PropertyType;
    var reviewProp = docType.GetProperty("Review");
    var reviewType = reviewProp.GetType();
project.EnvironmentalAssessment
        .GetType()
        .GetProperty(techStudy.DocumentProperty)
        .PropertyType
        .GetProperty("Review")
        .SetValue(reviewProp, _review, null);

任何见解将不胜感激。谢谢!

Answer 1

project.EnvironmentalAssessment
            .GetType()
            .GetProperty("SomeDocument")
            .PropertyType
            .GetProperty("Review")
            .SetValue(project.EnvironmentalAssessment.SomeDocument, _review, null);

或者如果您不知道文档属性的名称:

var docProp = project.EnvironmentalAssessment
            .GetType()
            .GetProperty(techStudy.DocumentProperty);
 docProp.PropertyType.GetProperty("Review")
            .SetValue(docProp.GetValue(project.EnvironmentalAssessment), _review, null);

Answer 2

您也可以使用动态类型来解决这个问题，这将使它更容易。我不知道在性能方面是否会比使用反射更有效。

dynamic project = ...;
var review = new Review() { .... };
project.EnvironmentalAessment.SomeDocument.Review = review;
