"void" 的值类型不能用于初始化 "System::string^" 的实体类型

Question

我正在关注 youtube 上创建表单的教程，但在完全按照他的操作进行操作时遇到此错误。找遍了也没弄明白

这是视频https://www.youtube.com/watch?v=lkhGpWUclc8&list=PLS1QulWo1RIZz6uDid--I09EOImRmPHS0&index=22

下面是代码

粗体部分是唯一抛出错误的部分

String^ strCharName = openCharDialog1->InitialDirectory = openCharDialog1->FileName;

private: System::Void openButton_Click(System::Object^  sender, System::EventArgs^  e) {

    Stream^ openCharacter;
    OpenFileDialog^ openCharDialog1 = gcnew OpenFileDialog;

    if (openCharDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
    {
        if ((openCharacter = openCharDialog1->OpenFile()) != nullptr )
        {

            String^ strCharName = openCharDialog1->InitialDirectory = openCharDialog1->FileName;

            MessageBox::Show(strCharName);

            openCharacter->Close();
        }
    }
}

Answer 1

错别字：

String^ strCharName = openCharDialog1->InitialDirectory + openCharDialog1->FileName;
                                                        ^

"void" 的值类型不能用于初始化 "System::string^" 的实体类型

a value type of "void" cannot be used to initialize an entity type of "System::string^"
