Pandas Dataframe or similar in C#.NET

I am currently working on implement the C# version of a Gurobi linear program model that was earlier built in Python. I have a number of CSV files from which I was importing the data and creating pandas dataframes, and I was fetching columns from those dataframes to create variables that I was using in my Linear Program. The python code for creating the variables using dataframes is as follows:

dataPath = "C:/Users/XYZ/Desktop/LinearProgramming/TestData"
routeData = pd.DataFrame.from_csv(os.path.join(dataPath, "DirectLink.csv"), index_col=None)
#Creating 3 Python-dictionaries from Python Multi-Dict using column names and keeping RouteID as the key
routeID, transportCost, routeType = multidict({x[0]:[x[1],x[2]] for x in routeData[['RouteID', 'TransportCost','RouteType']].values}) 

Example: If the csv structure is as follows:

RouteID  RouteEfficiency  TransportCost  RouteType
  1           0.8              2.00          F
  2           0.9              5.00          D
  3           0.7              6.00          R
  4           0.6              3.00          T     

The 3 variables should be:
RouteID: 1 2 3 4

TransportCost:

1:2.00
2:5.00
3:6.00
4:3.00

RouteType:

1:F
2:D
3:R
4:T

Now, I want to create a C# version of the above code that does the same task, but I learnt that C# doesn’t support dataframes. I tried looking for a few alternatives, but am unable to find anything. Please help me with this.
