Question

这是我想要从Java翻译成C＃的代码片段。我不确定导致错误的是什么，但我以前从未使用过ArrayLists和向量。在此先感谢!!

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

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

我尝试在C＃中执行以下操作：

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

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

我收到以下错误。我在Mac上使用Mono和Xamarin工作室。

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

和

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

Answer 1

请尝试以下方法。在Java中，您需要将数组传递给toArray方法，但在C＃（.NET）中这是不正确的。

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

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

参考

Java ArrayList.toArray

C# List.ToArray

需要帮助将代码片段从java转换为C＃等价物
