C#.NET中的Pandas Dataframe或类似版本 [英] Pandas Dataframe or similar in C#.NET

问题描述

我目前正在实现早期用Python构建的Gurobi线性程序模型的C#版本.我有许多CSV文件，从中导入数据并创建pandas数据框，并且从这些数据框中获取列以创建在线性程序中使用的变量.使用数据框创建变量的python代码如下:

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}) 

示例:如果csv结构如下:

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     

3个变量应为:路线ID:1 2 3 4

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

TransportCost:

TransportCost:

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

RouteType:

RouteType:

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

现在，我想创建上述代码的C#版本来执行相同的任务，但是我了解到C#不支持数据帧.我尝试寻找一些替代方法，但找不到任何东西.请帮助我.

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.
