ChangeType
Converts any type to another.
Source
using System.ComponentModel;
public static U ChangeType<U>(this object source, U returnValueIfException)
{
try
{
return source.ChangeType<U>();
}
catch
{
return returnValueIfException;
}
}
public static U ChangeType<U>(this object source)
{
if (source is U)
return (U)source;
var destinationType = typeof(U);
if (destinationType.IsGenericType && destinationType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
destinationType = new NullableConverter(destinationType).UnderlyingType;
return (U)Convert.ChangeType(source, destinationType);
}
Example
string a = "1234";
int b = a.ChangeType<int>(); //Successful conversion to int (b=1234)
string c = b.ChangeType<string>(); //Successful conversion to string (c="1234")
string d = "foo";
int e = d.ChangeType<int>(); //Exception System.InvalidCastException
int f = d.ChangeType(0); //Successful conversion to int (f=0)
