From version 1.2.2 ExpressionEvaluator manage ExpandObject class. ExpandoObject are object that can dynamically create new properties when you assign a value to it. It is also a dictionnary of properties. In ExpressionEvaluator you can use it as a object or as a dictionnary.
Here some examples :
myVar = new ExpandoObject();
myVar.X = 23.5;
myVar.Y = 34.8;
return myVar.X + myVar.Y;
// 58.3
myVar = new ExpandoObject();
myVar["Text"] = "Hello ";
return myVar["Text"] + " Bob" ;
// "Hello Bob"
myVar = new ExpandoObject();
myVar["Text"] = "Hello ";
return myVar.Text + " Bob" ;
// "Hello Bob"
myVar = new ExpandoObject();
myVar.Text = "Hello ";
return myVar["Text"] + " Bob" ;
// "Hello Bob"
obj = new ExpandoObject();
obj.Add = (x, y) =>
{
text = "The result is : ";
return text + (x+y).ToString();
};
return obj.Add(3, 4);
// "The result is : 7"
And from version 1.3.7 ExpandoObject can be created as anonymous objects:
obj = new {
Text = "Hello",
IntValue = 8,
Add = (x, y) =>
{
text = "The result is : ";
return text + (x+y).ToString();
}
};
