Type t = typeof(...);

var constructors = t.GetConstructors();
foreach (var con in constructors)
{
    Console.WriteLine(con.GetParameters().Length);
}

Ask for its parameters (through GetParameters()), then ask for the length of the array.

ConstructorInfo ctor = /* ... */
int numberOfArguments = ctor.GetParameters().Length;
