使用类型的字符串进行类型转换

Question

I have fully qualified class name which I have to use for type casting. I can get type using

someType=Type.GetType("TypeName"). 

After Deserializing I am getting object which I have to typecast into particular type ie TypeName.

I tried

obj = (someType) SXmlSerializer.Deserialize("TypeName", someData);

but that doesn't works . Is there any option available to do typecasting using only class name as string?

I have to convert it into someType because I have to modify value for property ie obj.SomeProperty = "AnotherValue" .

Answer 1

I have to convert it into someType because I have to modify value for property ie obj.SomeProperty = "AnotherValue".

But if you don't know the type at compile time, how do you know it has a SomeProperty property?

If you want to assume that it does and defer type-checking to runtime then you could use dynamic :

dynamic obj = SXmlSerializer.Deserialize("TypeName", someData);

then you can do

obj.SomeProperty = "AnotherValue";

Which will fail at runtime if the object does not have a SomeProperty property.

Casting only affects how methods are bound at compile-time. There's no value in casting if you don't know the type at compile-time.
