SerializationInfo.AddValue Method (String, Double)
Adds a double-precision floating-point value into the SerializationInfo store.
Assembly: mscorlib (in mscorlib.dll)
If two values are added with names that differ only by case, no exception will be thrown, which is not a recommended practice. However, adding two values with the exact same name will cause the SerializationException to be thrown.
