C# 多维数组上的 LINQ 查询

# 使用 LINQ 查询 C# 多维数组

csharp
int[,] twoDimensionalArray = new int[3, 3]
{
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};

csharp
var queryResult = from element in twoDimensionalArray
                  where element % 2 == 0
                  select element;

csharp
int[,] temperatureData = new int[7, 24]
{
    // 初始化温度数据，略
};
var maxTemperature = (from temperature in temperatureData
                      select temperature).Max();
Console.WriteLine($"最高温度是: {maxTemperature} 度");

csharp
int[,] studentGrades = new int[5, 3]
{
    // 初始化学生成绩数据，略
};
var passingStudents = from grade in studentGrades
                      where grade >= 60
                      select grade;
Console.WriteLine("及格学生的成绩列表:");
foreach (var grade in passingStudents)
{
    Console.WriteLine(grade);
}
