c# - Create Expression from PropertyInfo -

i'm using api expects expression<func<t, object>>, , uses create mappings between different objects:

map(x => x.id).to("id__c"); // expression "x => x.id" 

how can create necessary expression propertyinfo? idea being:

var properties = typeof(t).getproperties();  foreach (var propinfo in properties) {     var exp = // how create expression "x => x.id" ???      map(exp).to(name); } 

you need expression.property , wrap in lambda. 1 tricky bit need convert result object, too:

var parameter = expression.parameter(x); var property = expression.property(parameter, propinfo); var conversion = expression.convert(property, typeof(object)); var lambda = expression.lambda<func<t, object>>(conversion, parameter); map(lambda).to(name);
