Entity framework finding foreign keys

Question

I want to find all the foreign keys of an entity in my entity model.

I have used the following to get a list of all the properties for an entity:

var         


        

Answer 1

I worked out the solution:

var fk = _entities.MetadataWorkspace.GetItems<AssociationType>(DataSpace.CSpace).Where(a => a.IsForeignKey);
//check if the table has any foreign constraints for that column
var fkname = fk.Where(x => x.ReferentialConstraints[0].ToRole.Name == tablename).Where(x => x.ReferentialConstraints[0].ToProperties[0].Name == columnname);
//Get the corresponding reference entity column name
var refcol = fkname.Select(x => x.ReferentialConstraints[0].FromProperties[0].Name).First();
