Question

Hi I have created a List of objects and when I try to acces the properties I get an error saying that the object does not contain a definition for that property.Here is my code:

This is is where I create the List of objects:

public List<object> returnProductData(SetProduct product)
    {
        List<object> productData = new List<object>();

        var type = product.GetType();
        var properties = type.GetProperties();

        foreach (var propertyInfo in properties)
        {
            if( propertyInfo.GetValue(product , null) != null && propertyInfo.Name != "ProductName" &&
                propertyInfo.Name != "Brand" && propertyInfo.Name != "ProductPrice" && propertyInfo.Name != "ProductImagePath" )
            {
                productData.Add(new { propertyName = propertyInfo.Name , propertyValue = propertyInfo.GetValue(product , null).ToString()}) ;
            }
        }

        return productData;
    } 

This is where I try to acces it:

@foreach( var productData in ion)
            {
                <li>@productData.propertyName</li>
            }

When I try to acces it it says that the object does not contain a definition for propertyName.What am I doing wrong here?

Answer 1

The object hasn’t propertyName property.

If described scenario is very necessary and if you use .net 4.0 or above you can use dynamic like this:

public List<dynamic> returnProductData(SetProduct product)
    {
        List<dynamic> productData = new List<dynamic>();

        var type = product.GetType();
        var properties = type.GetProperties();

        foreach (var propertyInfo in properties)
        {
            if( propertyInfo.GetValue(product , null) != null && propertyInfo.Name != "ProductName" &&
                propertyInfo.Name != "Brand" && propertyInfo.Name != "ProductPrice" && propertyInfo.Name != "ProductImagePath" )
            {
                productData.Add(new { propertyName = propertyInfo.Name , propertyValue = propertyInfo.GetValue(product , null).ToString()}) ;
            }
        }

        return productData;
    } 

Usage:

@foreach( var productData in ion)
            {
                <li>@productData.propertyName</li>
            }
