Unable to handle Array

[KarthikKarunanithy]

Hi, I have just started to look into your library and it look and the test cases are helpful. I have a class object with array eg: Contact[] Contacts. Your library only supports IList and in GetExpression it throws an out of bounds exception in ProcessListStatement at var type param.Type.GetProperty(basePropertyName).PropertyType.GetGenericArguments()[0];

Can you please let me know if there is a different way to handle this?

Hi, have you found the solution for this?

I have the same issue.

Hi , Yes, In FilterBuilder.cs I had to change the method ProcessListStatement.. below for reference

        if(propType.IsArray)
        {
            type = propType.GetElementType();
        }
        else
        {
            type = propType.GetGenericArguments()[0];
        }

Hi, thank you. I just tried it but with no luck.

I modified some in the ProcessListStatement() method:

...
var propType = param.Type.GetProperty(basePropertyName).PropertyType;
var type = propType.IsArray ? propType.GetElementType() : propType.GetGenericArguments()[0];
...

My test case:

var indexes = new Dictionary<long, Index>();
indexes.Add(1, new Index { Position = 1000, Values = new object[3] { "Welly", "Chandra", 26 } });
indexes.Add(2, new Index { Position = 1001, Values = new object[3] { "Darma", "Angelo", 25 } });
indexes.Add(3, new Index { Position = 1002, Values = new object[3] { "Abby", "Yeremia", 28 } });
indexes.Add(4, new Index { Position = 1003, Values = new object[3] { "Yonathan", "Gunawan", 22 } });
indexes.Add(5, new Index { Position = 1004, Values = new object[3] { "Aldy", "Santoso", 24 } });
var filter = new Filter<Index>();
filter.By("Values[1]", Operation.EqualTo, "Chandra", Connector.Or);
filter.By("Values[2]", Operation.EqualTo, 28);

public class Index
{
   public long Position { get; set; }

   public object[] Values { get; set; }
}

Error message: System.ArgumentException: '1' is not a member of type 'System.Object' (Parameter 'propertyOrFieldName')
