Dear Abinash-san,
I googled "C# Serial" and found the following URL
SerialPort クラス (System.IO.Ports) | Microsoft Docs
It was a sample chat program, so I modified it to work with the PSoC Program,
namely, I change
(1) line 54
From
_serialPort.WriteLine(
String.Format("<{0}>: {1}", name, message));
To
_serialPort.WriteLine(
message);
(2) commented line 39 and 40, as PSoC will not care my name
// Console.Write("Name: ");
// name = Console.ReadLine();
The total source is now
========================
// Use this code inside a project created with the Visual C# > Windows Desktop > Console Application template.
// Replace the code in Program.cs with this code.

========================
Then I modified PSoC's program as below
main.c
========================
#include "project.h"
#define LED_ON 1u
#define LED_OFF 0u
#define USBFS_DEVICE (0u)
char detorecibido ;
int main(void)
{
uint16 count;
char c ;
int i ;
CyGlobalIntEnable; /* Enable global interrupts. */
/* Start USBFS operation with 5-V operation. */
USBUART_Start(USBFS_DEVICE, USBUART_5V_OPERATION);
for(;;) {
/* Host can send double SET_INTERFACE request. */
if (0u != USBUART_IsConfigurationChanged())
{
/* Initialize IN endpoints when device is configured. */
if (0u != USBUART_GetConfiguration())
{
/* Enumeration is done, enable OUT endpoint to receive data
* from host. */
USBUART_CDC_Init();
}
}
/* Service USB CDC when device is configured. */
if (0u != USBUART_GetConfiguration())
{
/* Check for input data from host. */
if (0u != USBUART_DataIsReady())
{
count = USBUART_GetCount() ;
for (i = 0 ; i < count ; i++ ) {
c = USBUART_GetChar() ;
switch(c) {
case 'd':
case 'D':
LED_Write(LED_OFF) ;
USBUART_PutString("_\n\r") ;
break ;
case 'l':
case 'L':
LED_Write(LED_ON) ;
USBUART_PutString("*\n\r") ;
break ;
default:
break ;
}
}
}
}
}
}
========================
After compiling both of the project,
(1) Start PSoC's program
(2) Start C# program
The result output of C# program was
when I typed "l" and enter, the LED turns on and "*" was written
when I typed "d" and enter, the LED turns off and "_" was written
UartTest200727 is for .NET/C#
uart_test_050_200727C is for PSoC 5LP
