需要帮助将代码片段从java翻译成C#等价物吗

下面是我想从Java翻译成C的代码片段。我不确定是什么导致了错误，但我以前从未使用过ArrayList和Vector。提前谢谢

//Java class definitions, constructors, fields, methods etc here. 
//sphbasis is a Vector object.

    public SphericalHarmonicDecomposition[] getSphericalHarmonicBasis() {
    return (SphericalHarmonicDecomposition[])(sphbasislist.toArray(
    new SphericalHarmonicDecomposition[sphbasislist.size()]));
}

我试着用C#做了以下几件事：

我得到以下错误。我在mac上使用Mono和Xamarin studio

Error CS1502: The best overloaded method match for 
`System.Collections.ArrayList.ToArray(System.Type)' 
has some invalid arguments (CS1502) (projectx)

及

请尝试以下方法。在Java中，需要将数组传递给

toArray

方法，但在C#（.NET）中这是不正确的

工具书类

无论如何，您都应该使用通用列表

Error CS1502: The best overloaded method match for 
`System.Collections.ArrayList.ToArray(System.Type)' 
has some invalid arguments (CS1502) (projectx)

Error CS1503: Argument `#1' cannot convert    
`matdcal.engine.model.SphericalHarmonicDecomposition[]' expression 
to type `System.Type' (CS1503) (projectx)

//C# class definitions, constructors, fields, methods etc here. 
//sphbasis is a ArrayList object.

    public SphericalHarmonicDecomposition[] getSphericalHarmonicBasis() {
    return (SphericalHarmonicDecomposition[])(sphbasislist.ToArray());
    }
