I have a line of code that uses "to" function in std.conv for a purpose 
like:

int index = to!int( user_apply[ 4 ] ); // string to int

When the user_apply[ 4 ] has value, there is no problem; but when it is 
empty: ""
it throws an ConvException exception and I want to avoid this exception.

currently I have to use a dummy catch:
try{
     index = to!int( user_apply[ 4 ] );
} catch( ConvException conv_error ){
     // nothing
}

I no need to handle that, so is there any way to prevent this exception?

Use the "parse" family: https://dlang.org/phobos/std_conv.html#parse --
