Question

an example code what I try to do will surely do better than my english:

public bool IsNumericValueInBounds (string value, Type numericType) {   double d = double.NaN;         bool inBounds = (bool)numericType.GetMethod ('TryParse').Invoke (null, new object[] { value, d });    return inBounds; } 

Unfortunately the TryParse method needs an out parameter so this doesn’t work. any ideas how to solve this?

(ps.: would’nt this be a nice example for duck typing? – because i know every numericType has an ‘TryParse’ or I am mistaken?)

public static bool TryParse( string text, out int number ) { .. }  MethodInfo method = GetTryParseMethodInfo(); object[] parameters = new object[]{ '12345', null } object result = method.Invoke( null, parameters ); bool blResult = (bool)result; if ( blResult ) {     int parsedNumber = (int)parameters[1]; }
