How do i remove a specific collection from my model in C# -

this model:

    public class obsmodel : bindablebase     {           private string _obsname = string.empty;         public string obsname         {             { return this._obsname; }             set { this.setproperty(ref this._obsname, value); }         }          private string _obscolor = string.empty;         public string obscolor         {             { return this._obscolor; }             set { this.setproperty(ref this._obscolor, value); }         }          private string _obsvalue = string.empty;         public string obsvalue         {             { return this._obsvalue; }             set { this.setproperty(ref this._obsvalue, value); }         } } 

i can populate model using object.

observablecollection<obsmodel> lastobsresults = new observablecollection<obsmodel>(); 

but how can remove particular collection if have example observation name string variable using code below?

latsobsresults.remove( put here); 

you remove object collection passing in object remove. can done through linq so:

lastobsresults.remove(lastobsresults.firstordefault(obs => obs.obsname == name));
