c# - Why am I getting an error indicating that my variable doesn't exist, when I've already defined it? -

i error indicating myrandomarray doesn't exist in current context. how access variables across classes in c# winforms application?

public void quiz_load(object sender, eventargs e) {     string[] myrandomarray = getwordlist(); }  private void timer1_tick(object sender, eventargs e) {     somefunction(myrandomarray);/// myrandomarray doesn't exist in current context. } 

you've defined array, only in scope of quiz_load method, scope of timer1_tick has no knowledge of it. if declare instance member of class, accessible instance method:

private string[] myrandomarray;  public void quiz_load(object sender, eventargs e) {     this.myrandomarray = getwordlist(); }  private void timer1_tick(object sender, eventargs e) {    somefunction(this.myrandomarray); // no problem }
