remove part of string from textbox with Replace [duplicate]

Question

I have a string in textbox like this

 xxxxxxxxxxx    310041              xxxxx   xxxxxx    xxxx xxxx
  RTE STAT: 00 AUTH ID RESP:         ERR FLAG: 0   PEM: M (02)   ATC: 000000
    RVSL REASON: 00       TELLER/SERIAL:          /         TERM CAP: 5 (EMV)

i need to remove this RTE STAT: 00 AUTH ID RESP: ERR FLAG: 0 to

txtRemark.Text.Replace("  RTE STAT: 00 AUTH ID RESP:         ERR FLAG: 0   ", "")

but nothing happened i try with regex but it's not happened too

result must be like this

 xxxxxxxxxxx    310041              xxxxx   xxxxxx    xxxx xxxx
 PEM: M (02)   ATC: 000000
 TERM CAP: 5 (EMV)

Did you assign the value to the txtRemark.Text? txtRemark.Text = txtRemark.Text.Replace(" RTE STAT: 00 AUTH ID RESP: ERR FLAG: 0 ", "") — Wiktor Stribiżew

As per the documentation, the .Replace method yields back the replace string. You will need to change your code from txtRemark.Text.Replace(" RTE STAT: 00 AUTH ID RESP: ERR FLAG: 0 ", "") to txtRemark.Text = txtRemark.Text.Replace(" RTE STAT: 00 AUTH ID RESP: ERR FLAG: 0 ", "").
