MethodInfo.Invoke with out Parameter
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];
}
