Conversion of Java to C# code

Question

All,

I am currently trying to convert some lines of code from Java to C# using Visual Studio 2013. However the lines below is causing me some issues:

final double testdata[][] = {{patientTemperatureDouble, heartRateDouble, coughInteger, skinInteger}};
result[i] = BayesClassifier.CalculateProbability{testdata[k],category[i]};

Any clarification as to converting the array to a suitable c# format would be greatly appreciated, I have attempted using readonly and sealed but I've had no luck.

Thanks

As asked in the comment, if your testdata is a class' field, you could use readonly keyword. But if it is a local variable/method parameter, there is no direct equivalent in C#. In either case, given a set of double[], you can initialize a double[][] jagged array by removing one of the curly brackets:

readonly double[][] testdata = new double[][] { //for class field
    patientTemperatureDouble, //is double[]
    heartRateDouble, //is double[]
    coughInteger, //is double[]
    skinInteger //is double[]
};

double[][] testdata = new double[][] { //for local variable
    patientTemperatureDouble, //is double[]
    heartRateDouble, //is double[]
    coughInteger, //is double[]
    skinInteger //is double[]
};
