java - 需要帮助将代码片段从 java 转换为 C# 等价物

Question

这是我想从 Java 转换为 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 ArrayLists 和 vector 。提前致谢!!

//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 Studio。

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

请尝试以下操作。在 Java 中，您需要将数组传递给 toArray 方法，但这在 C# (.NET) 中是不正确的。

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

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

Java ArrayList.toArray

C# List.ToArray
