c# - How to calculate a score when you drag and drop information from a textbox into multiple DrapDrop event -

i creating simple game application in windows forms. can drag information textbox , drop dragdrop event 1 mdi application another. ok problem having have multiple dragdrop events , trying calculate score of them.

what have tried far this.

public void score(int calcscore) {     lblscore.text += calcscore.tostring(); }  private void square_dragdrop(object sender, drageventargs e) {     if(shape.contains("square"))     {         int calcscore = 0;         calcscore++;         score(calcscore);     } }      private void circle_dragdrop(object sender, drageventargs e) {     if(shape.contains("circle"))     {         int calcscore = 0;         calcscore++;         score(calcscore);     } }     

the problem add score string result 11 instead of 2.

if try this:

public void score(int calcscore) {     int totalscore =0;     totalscore = totalscore + calcscore;     lblscore.text += totalscore.tostring(); } 

the problem once initialize totalscore sets total score 0 totalscore 1.

how can score calculated this?

1.

public void score(int calcscore) {     lblscore.text += calcscore.tostring(); } 

this cocatenation of strings. so:

"1" + "1" = "11"; 

just

"cat"+"cat" = "catcat"; 

2.

initialise

int totalscore =0;  int calcscore =0; 

at class level. every time use dragdrop or method score(int calcscore) resetting these values zero.
