您不知道.如果您想要一个双精度数组，可以尝试一下.

You don''t. If you want an array of doubles, you can try this.

double value1 = 0.0;
double[] valueArray = new double[1];
valueArray[0] = value1;

或

or

double value1 = 0.0;
double[] valueArray = new double[]{value1};

通常来说，没有这种转换.您为什么要提出要求(即确切地知道您的要求，也许我们可以为您提供解决方案?)?

Generally speaking there is NOT such a conversion. Why are you asking for (i.e. knowing exactly your requirements maybe we can provide you a work around)?

，或者通常是

public static T[] ToArray<T>(T t)
        {            
            return new T[] { t };
        }

public static Array ToArray(Object o)
        {
            Array result = Array.CreateInstance(o.GetType(), 1);
            result.SetValue(o, 0);
            return result;
        }
