c# - Can you call a place in an array with a char that is a valid int but defined as a string? -

for example, have array (called array1): {"1","2","3"}

and string (called string1): "0"

can following: array1[string1]

and have equal: "1"

i have checked how can evaluate c# expression dynamically? , call c# function defined in string did not understand answers. apologize.

when try string1 = int.parse(string1); error:

or string1 = convert.toint32(string1); :

cannot implicitly convert type 'int' 'string'

to elaborate, (sorry if description wasn't clear), code this:

btnname =  btn.name.tostring(); //btnname example == btn01 btnco1 = btnname[3].tostring(); // btnco1 equal "0" btnco2 = btnname[4].tostring(); //btnco2 equal "1" btnco1 = convert.toint32(btnco1); //i want btnco1 int use : btnco2 = convert.toint32(btnco2);    grid[btnco1][btnco2] //grid jagged array 

you have parse string int, preferably using tryparse:

int idx; if (int32.tryparse(string1, out idx)) console.writeline(array1[idx]); 

other way using convert.toin32. might throw exception if string1 cannot converted int, example if contains "hello world".

edit concerning yours: can´t change variables data-type once you´ve declared it. if btnco1 is string can´t change int, have define new variable it:

int idx1 = convert.toint32(btnco1); int idx2 = convert.toint32(btnco2);  dosomething(grid[idx1][idx2]);
