Question

以下是我正在运行的脚本。

脚本运行正常。它提供了适当的输出，但它正在从几列中删除前导零。请建议如何保留整数字段的前导零。

我正在使用

$res.data.Tables[0] | ConvertTo-Csv -NoType | ForEach-Object {$_.Replace('"','')} | Out-file $fileName -Force"

用于将数据导出到CSV文件。请建议如何保留前导零（至少2位小数）。

        foreach ($outp in $outparams.Keys) {
            $p = $cmd.Parameters.Add("@$outp", (get-paramtype $outparams[$outp])) 
            $p.Direction=[System.Data.ParameterDirection]::Output

整数没有“前导零”。如果要导出格式化输出，则需要将相应字段转换为格式化字符串，例如像这样：

$res.data.Tables[0] |
  Select-Object FieldA, FieldB, @{n='FieldC';e={'{0:d2}' -f $_.FieldC}},
                @{n='FieldD';e={'{0:d2}' -f $_.FieldD}}, FieldE, ... |
  ConvertTo-Csv -NoType |
  ...

使用ExportTo-Csv cmdlet时会丢弃前导零
