Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Object. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).


The method firstly tries to use registered direct conversions between source and target types, then attempts to perform the conversion via IConvertible types and registered TypeConverters. If these attempts fail, then the registered conversions tried to be used for intermediate steps, if possible. As an ultimate fallback, the String type is attempted to be used as intermediate conversion.

New conversions can be registered by the RegisterConversion extension methods.


The registered conversions are tried to be used for intermediate conversion steps if possible. For example, if a conversion is registered from DateTime to Int64, then conversions from DateTime to Double becomes automatically available using the Int64 type as an intermediate conversion step.

targetType can be even a collection type if obj is also an IEnumerable implementation. The target collection type must have either a default constructor or a constructor that can accept a list, array or dictionary as an initializer collection.


ArgumentExceptionobj cannot be converted to targetType.
