Tokenizer and Parser is based on Vanlightly DslParser Project
I've created some new Tokens and modified the MatchConditions so it can work with Properties of the Objects.
The Linq-Where Extension Method accepts a String as Parameter. This String will be tokenized by the Tokenizer and parsed by the DSL Parser. After parsing the Method BuildExpression builds the Expressions for the Original Linq-Where Method.
Since I don't have enough time there will be no or not much support for this.
Usage:
IList<MyDataElement> liste = new List<MyDataElement>();
ObjectListView<MyDataElement> objList = new ObjectListView<MyDataElement>();
objList.DataSource = liste;
bindingSource1.DataSource = objList;
bindingSource1.Filter = "x > 3";Register Custom Function:
class TestFunction {
public static bool containsTestString(string x)
{
return x.Contains("test");
}
}
// First Parameter: Name of the Function in the Filter
// Second Parameter: MethodInfo Object
ObjectBindingListView.LinqExtension.MethodInfos.Add("test", typeof(Form1).GetMethod("containsTestString"));
bindingSource1.Filter = "test(x123)";
