Winform call external exe, Windows 7 under normal win10 error

The code is as follows:
The Process of p=new Process ();
P. tartInfo. FileName="pre_test \ \ pre_test exe";//need to perform file, I put him in the site directory
.//p. tartInfo FileName="CMD. Exe";//need to perform file, I put him in the site directory
P. tartInfo. UseShellExecute=false;//necessary
P. tartInfo. RedirectStandardOutput=true;//output parameters setting
P. tartInfo. RedirectStandardInput=true;//incoming parameters setting
P. tartInfo. CreateNoWindow=true;
//p. tartInfo. The Arguments="D: \ \ the PPP";//parameters separated by Spaces, if a parameter is empty, can pass in ""

.//p. tartInfo StandardErrorEncoding=System. Text.. Encoding UTF8;//incoming parameters setting
P. tart ();
P. tandardInput. WriteLine (" d: \ \ result ");
StreamReader _StreamReader=p. tandardOutput;
The string line=_StreamReader. ReadToEnd ();
String _Resultindex=line. The Substring (line. IndexOf (" [[") + 2, 6);
Console. WriteLine ($" to obtain the value of the is: {_Resultindex} ");
P.W aitForExit ();//wait for program execution of the exit process
P.C lose ();
_StreamReader. Close ();
Based on under win10 p. tandardInput didn't receive the parameters
