无法将类型'int？[]'隐式转换为'int []

Question

我喜欢这段代码：

    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 []'

知道如何修复错误？

提前谢谢。

Answer 1

只需更改您的陈述

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

要

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 };
