c# - Check table for relations before deleting -

i'm trynig check if parameter has values before deleting it. if parameter has values should return true. using code:

private bool hasvalue() {     return factory.definitions.calculationparametersvalues         .list().any(a => factory.definitions.calculationparameters             .list().any(b => a.calculationparameterid == b.id)).any(); }  //factory.definitions.calculationparametersvalues.list() lists data database table //factory.definitions.calculationparameters.list() lists data database table 

values contain parameter's id calculationparameterid.

it returns true. don't know i'm doing wrong. correct me please ?

try this:

private bool hasvalue(int idparameter) {     return factory.definitions.calculationparametersvalues.any(a=>a.id== idparameter); }
