c# - 无法将类型 'int?[]' 隐式转换为 'int[]

Question

我哈哈这段代码：

    private FoundContours SelectFromFoundSamples(FoundContours foundACContours, FoundContours foundFNContours, FoundContours foundBlurContours, FoundContours foundFilteredContours)
    {

        int? num = null;

        int? a = null, b = null, c = null, d = 10;


        int?[] numbers = new[] { foundACContours.Count, foundFNContours.Count, foundBlurContours.Count, foundFilteredContours.Count };

        int? max = numbers.Max();
    }

在这一行：

int?[] numbers = new[] { foundACContours.Count, foundFNContours.Count, foundBlurContours.Count, foundFilteredContours.Count };

我收到此错误：

“不能将类型'int？[]'隐式转换为'int []'

知道如何解决错误吗？

先感谢您。

Answer 1

只是改变你的说法

int?[] numbers = new[] { foundACContours.Count, foundFNContours.Count, 
                         foundBlurContours.Count, foundFilteredContours.Count };

到

int?[] numbers = new int?[] { foundACContours.Count, foundFNContours.Count, 
                             foundBlurContours.Count, foundFilteredContours.Count };

Answer 2

int?[] numbers = new int?[] { foundACContours.Count, foundFNContours.Count, foundBlurContours.Count, foundFilteredContours.Count };
