C＃中数组的Java .length等效于什么？

Question

I'm new to C#, and I'm trying to convert this code from java into C#.

    static public double euclidean_2(double[] x, double[] y)
    {
        if (x.length != y.length) throw new RuntimeException("Arguments must have same number of dimensions.");

        double cumssq = 0.0;
        for (int i = 0; i < x.length; i++)
            cumssq += (x[i] - y[i]) * (x[i] - y[i]);

        return cumssq;
    }

I know java uses .length but what is the equivalent in C# since I keep getting an error

Thanks

Answer 1

In C# public members should be capitalized:

for (int i = 0; i < x.Length; i++)
    cumssq += (x[i] - y[i]) * (x[i] - y[i]);

Answer 2

For the arrays, you want the Length property.

Also the exception type should be changed.

I think that covers it.

Answer 3

the length should be Length , since members that are public should be capitalized so your code in C# should be like this:

public static double euclidean_2(double[] x, double[] y){
    if (x.Length != y.Length){
        throw new Exception("Arguments must have same number of dimensions.");
    }
    double cumssq = 0.0;
    for (int i = 0; i < x.Length; i++){
        cumssq += (x[i] - y[i]) * (x[i] - y[i]);
    }
    return cumssq;
}

also take note of the keyword Exception instead of Runtime Exception
