Question

使用过：

            private string RunScript(string storeNumber)
    {
        //string importSQL = "Import-Module sqlserver -DisableNameChecking";
        //string executionPolicy = "Set-ExecutionPolicy -ExecutionPolicy Unrestricted";
        //string script = "ping databaseName";
        //string script = "sqlcmd - h - 1 - Q \"set nocount on;SELECT System_Date FROM Location_Codes\" - d pos - S databaseName | out-string";
        string script = "invoke-sqlcmd -Query \"use pos set nocount on; SELCECT System_date FROM location_codes\" -serverinstance databaseName| out-string";
        Runspace runspace = RunspaceFactory.CreateRunspace();
        runspace.Open();

        Pipeline pipeline = runspace.CreatePipeline();
        //pipeline.Commands.AddScript(importSQL);
        //pipeline.Commands.AddScript(executionPolicy);
        pipeline.Commands.AddScript(script);


        Collection<PSObject> results = pipeline.Invoke();

        runspace.Close();

        StringBuilder stringBuilder = new StringBuilder();
        foreach(PSObject obj in results)
        {
            stringBuilder.AppendLine(obj.ToString());
        }
        MessageBox.Show(stringBuilder.ToString());
        return stringBuilder.ToString();

    }

尝试sqlcmd时，我没有收到任何错误，但没有返回任何内容（即使直接在Powershell中键入命令也可以得到我想要的数据）

尝试调用invoke-sqlcmd时，抛出CmdletInvocationException。对于该错误，我添加了

      <startup useLegacyV2RunttimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>

添加了ping命令作为测试。那确实返回了数据。任何帮助将不胜感激！

这可能对您有帮助从
更改字符串脚本=“ invoke-sqlcmd -Query \”使用pos设置nocount； SELCECT System_date FROM location_codes \“ -serverinstance databaseName | out-string”;

收件人

字符串脚本= @“ invoke-sqlcmd -Query'use pos set nocount on 走从位置代码的-serverinstance databaseName |中选择System_date字符串”；

我使用单个冒号的原因是，对于Powershell”用来表示字符串 而且我不认为Powershell会识别“;”用于sql分隔符。

在C＃中的Powershell脚本中运行sqlcmd或invoke-sqlcmd
