c# - 无法将类型 'int?[]' 隐式转换为 'int[]

Question

我哈哈这一段代码:

    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 };

我收到这个错误:

“无法将类型‘int?[]’隐式转换为‘int[]’

知道如何修复错误吗？

提前谢谢你。

只是改变你的声明

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

到

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