c# - Implicitly convert type 'string' to 'bool' -

i have deal question: filter student in list result "pass". when write code in picture below, return wrong caution this: cannot implicitly convert type 'string' 'bool'. although used convert.toboolean(t.result) can't work?

help me!

to filter student in list result "pass" need add condition as:

lst.where(t => t.result=="pass").tolist(); 

you can same boolean property instead string, property definition like:

public bool  result {     { return score > 25; }            } 

so iterative condition filtering student in list result "pass"(score > 25)

lst.where(t => t.result).tolist();
