我有以下命令,它返回我 null object 。当我在 PowerShell 窗口中单独运行命令时,我得到了正确的结果。下面是调用命令的 PowerShell 方法以及我定义的 PowerShell 命令。我基本上希望返回一个字符串值。请让我知道我做错了什么?
C#方法:
public string RunScript( string contentScript, Dictionary<string, EntityProperty> parameters)
{
List<string> parameterList = new List<string>();
foreach( var item in parameters )
{
parameterList.Add( item.Value.ToString() );
}
using( PowerShell ps = PowerShell.Create() )
{
ps.AddScript( contentScript );
// in ContentScript I get "Get-RowAndPartitionKey" on debugging
ps.AddParameters( parameterList );//I get list of strings
IAsyncResult async = ps.BeginInvoke();
StringBuilder stringBuilder = new StringBuilder();
foreach( PSObject result in ps.EndInvoke( async ) )
// here i get result empty in ps.EndInvoke(async)
{
stringBuilder.AppendLine( result.ToString() );
}
return stringBuilder.ToString();
}
}
}
我的 Powershell GetRowAndPartitionKey
cmdlet 定义,上面的代码试图调用它:
public abstract class GetRowAndPartitionKey : PSCmdlet
{
[Parameter]
public List<string> Properties { get; set; } = new List<string>();
}
[Cmdlet( VerbsCommon.Get, "RowAndPartitionKey" )]
public class GetRowAndPartitionKeyCmd : GetRowAndPartitionKey
{
protected override void ProcessRecord()
{
string rowKey = string.Join( "_", Properties );
string pKey = string.Empty;
WriteObject( new
{
RowKey = rowKey,
PartitionKey = pKey
} );
}
}
}
