当我通过 Metro 应用程序插入文件路径(通过浏览到文件夹路径)时,我得到的值(在数据库中)与下面的路径相同,其中有双斜杠。因此,它总是给出这个错误:
System.Management.Automation.dll 中发生“System.Management.Automation.ParameterBindingException”类型的异常,但未在用户代码中处理
这是带有一些用于测试的虚拟值的代码:
public bool InsertNewVm(VirtualMachineDetails addVmDetails)
{
bool addVmMsg = true;
//string vmName = addVmDetails.VmName.ToString();
addVmDetails.VmName = "NewMedia";
addVmDetails.VmRam = "512MB";
addVmDetails.VmHardDisk = "C:\\Users\\Public\\Documents\\Hyper-V\\Virtual hard disks\\Win8 Virtual Machine.vhdx";
addVmDetails.VmOS = "Windows 8";
addVmDetails.VmIncSoftware = "Visual Studio 2012";
addVmDetails.VmNetwork = "Virtual Switch";
addVmDetails.VmDiploma = "INE";
addVmDetails.VmYear = "Year 1";
addVmDetails.VmModule = "New Media";
conn.Open();
if (addVmDetails.VmName != "")
{
string checkkVmAdd = "SELECT * FROM VirtualMachine where VMName = '" + addVmDetails.VmName.ToString() + "'";
SqlCommand cmdValidate = new SqlCommand(checkkVmAdd, conn);
SqlDataReader dr = cmdValidate.ExecuteReader();
while (dr.Read())
{
if (dr["VMName"].ToString() == addVmDetails.VmName.ToString())
{
addVmMsg = false;
return addVmMsg;
}
}
dr.Close();
string insertVm = "INSERT INTO VirtualMachine(VMName, Ram, HardDisk, OS, IncludedSoftware, SwitchName, Diploma, Year, Module) values ('" + addVmDetails.VmName.Trim() +
"','" + addVmDetails.VmRam.Trim() + "','" + addVmDetails.VmHardDisk.Trim() + "','" + addVmDetails.VmOS.Trim() + "','" + addVmDetails.VmIncSoftware.Trim() + "','" + addVmDetails.VmNetwork.Trim() +
"','" + addVmDetails.VmDiploma.Trim() + "','" + addVmDetails.VmYear.Trim() + "','" + addVmDetails.VmModule.Trim() + "')";
SqlCommand cmdInsert = new SqlCommand(insertVm, conn);
cmdInsert.ExecuteNonQuery();
PowerShell ps = PowerShell.Create();
ps.AddCommand("New-VM");
ps.AddParameter("Name", addVmDetails.VmName.Trim());
ps.AddParameter("VHDPath", addVmDetails.VmHardDisk.Trim());
ps.AddParameter("SwitchName", addVmDetails.VmNetwork.Trim());
ps.AddParameter("MemoryStartupBytes", addVmDetails.VmRam.Trim());
var result = ps.Invoke();
conn.Close();
return addVmMsg;
}
else
{
addVmMsg = false;
}
return addVmMsg;
}
编辑:
事实证明,错误不是来自文件路径。当我想指定内存大小时发生错误。当我在下面注释掉这一行时,可以创建虚拟机而不会出错:
ps.AddParameter("MemoryStartupBytes", addVmDetails.VmRam.Trim())
因此,我不确定在指定内存大小时如何准确地创建而不会出错。在 PowerShell 中,我必须在为内存大小输入的任何数字之后包括 MB 或 GB 等,因为没有它,我无法创建虚拟机。
任何帮助是极大的赞赏。
谢谢。
