问如何将记录转换为元组？

// I want to generate lots of sample data for the first three columns
// And I would like to avoid creating giant record types in order to
// do this task as the csv's are always changing and the records would
// have to change as well
type CumbersomeCSVRow = // 17 fields now, but imagine 212
    string * string * string * Option<int> * string * 
    Option<int> * string * string * string * string * 
    string * string * Option<float> * string * 
    Option<float> * Option<float> * string

// Here is a sample row of data
let sampleCumbersomeRow : CumbersomeCSVRow = 
    ("First","Second","Third",Some(52),"MSCI",None,"B74A123","",
     "Airlines","Transportation","","",Some(1.04293),"Updated",
     Some(0.95),Some(56.7423),"Measured")

// Record type of the sample data that I want to 'insert' into the cumbersome data type
type FirstThreeStrings = 
    { First : string; Second : string; Third : string}

// and some instances of the new data
let generatedFrontMatters = 
    // imagine lots of sample data and workflows to create it, hence the records
    seq { for letter in ["A";"B";"C"] -> 
            { First  = letter;
              Second = letter + letter
              Third  = letter + letter + letter } }
