c# - C#、GetProperty 绑定源、作者表适配器

Question

我对 GetProperty 有疑问

partial class MyForm : Form
{
    ...

    public System.Windows.Forms.BindingSource authorBindingSource = new ...;
    public MethodicalWorkDataSetTableAdapters.authorTableAdapter authorTableAdapter = new ...;

    ...


    public static object GetPropValue(object src, string propName)
    {
        return src.GetType().GetProperty(propName).GetValue(src, null);
    }

    public void someFunction()
    {
        GetPropValue( this, "authorBindingSource" ); // returns null
    }
}

请帮助我，函数 GetPropValue 工作正常，除了“authorTableAdapter”和“authorBindingSource”

Answer 1

在您的示例中，authorTableAdapterandauthorBindingSource是fields，而不是properties。更改GetProperty为GetField。

Answer 2

使用GetMember而不是GetProperty
