Question

我试图使用具有参数集的另一个PowerShell函数来调用具有参数集的PowerShell函数。在下面的代码中，我想使用Entry-Point或-ABC开关（不是同时不是）来调用-DEF。但是，当我使用任意数量的参数运行Entry-Point时，下面将得到AmbiguousParameterSet异常。

function My-Function {
    [CmdletBinding(DefaultParameterSetName='ABC')]
    Param(
        [Parameter(Mandatory=$false, ParameterSetName='ABC', Position=1)]
        [switch] $ABC,

        [Parameter(Mandatory=$false, ParameterSetName='DEF', Position=1)]
        [switch] $DEF,

        [switch] $Extra
    )

    echo $ABC
    echo $DEF
    echo $Extra
}


function Entry-Point {
    [CmdletBinding(DefaultParameterSetName='ABC')]
    Param(
        [Parameter(Mandatory=$false, ParameterSetName='ABC', Position=1)]
        [switch] $ABC,

        [Parameter(Mandatory=$false, ParameterSetName='DEF', Position=1)]
        [switch] $DEF,

        [switch] $Extra
    )

    My-Function -ABC:$ABC -DEF:$DEF -Extra:$Extra
}

My-Function : Parameter set cannot be resolved using the specified named
parameters.
At line:24 char:1
+ My-Function -ABC:$ABC -DEF:$DEF -Extra:$Extra
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [My-Function], ParameterBindingException
    + FullyQualifiedErrorId : AmbiguousParameterSet,My-Function

如何将参数-ABC和-DEF从功能Entry-Point传递到功能My-Function（无论是否已指定）？

快速的答案是喷溅。 PowerShell使您可以将哈希表作为函数的参数来呈现（使用@代替$），并使用哈希表的键作为参数名称，这些值就是参数值。

此外，每个高级功能都会自动将$ PSBoundParameters设置为传入参数的哈希表。

所以...您可以说： #include <stdio.h> #include <stdlib.h> #include <time.h> #include <omp.h> typedef struct MATRIX { unsigned int row = 0, column = 0; int data[0][0]; }; void generateMatrixsParallel(struct MATRIX matrixA, struct MATRIX matrixB) { srand((unsigned int) time(NULL)); printf("\n%d\n", matrixB.row); #pragma omp for for(int row = 0; row < matrixA.row; row++) { for(int column = 0; column < matrixA.column; column++) { matrixA.data[row][column] = rand(); } } printf("\n%d\n", matrixB.row); #pragma omp for for(int row = 0; row < matrixB.row; row++) { for(int column = 0; column < matrixB.column; column++) { matrixB.data[row][column] = rand(); //printf("MATRIX B[%d][%d]: [%d]\n", row, column, matrixB.data[row][column]); } } } int main() { static struct MATRIX matrixA; static struct MATRIX matrixB; printf("BETWEEN WITH QUANTITY OF LINES [VECTOR A]: "); scanf("%d", &matrixA.row); printf("BETWEEN WITH QUANTITY OF COLUMN [VECTOR A]: "); scanf("%d", &matrixA.column); printf("BETWEEN WITH QUANTITY OF LINES [VECTOR B]: "); scanf("%d", &matrixB.row); printf("BETWEEN WITH QUANTITY OF COLUMN [VECTOR B]: "); scanf("%d", &matrixB.column); #pragma omp parallel firstprivate(matrixA, matrixB) num_threads(3) { #pragma omp master printf("AGUARDE... A THREAD MASTER ESTÁ GERANDO AS MATRIZES!", omp_get_thread_num()); generateMatrixsParallel(matrixA, matrixB); } return 0; }

将ParameterSet值传递给其他ParameterSet会导致AmbiguousParameterSet异常
