error using float for array to string

[C# Programming]

The following:

float.m_result = float.Parse(m_store[0].ToString());

is generating an error:

'float' does not contain a definition for 'm_result'.

The .net help message is:

'type' does not contain a definition for 'identifer'

Not sure which direction I need here. I am new to c#, appreciate help.

Thanks
