How to remove last word separated by a dot (...)

Question

How to remove last word separated by a dot without displaying messageBox. Just displaying inside textbox Hi, My codes need some corrections. I have into my textbox numbers separated by dot (for example: 1.5.6.7), then I need to remove the last number with the dot before (for example colored in red: 1.5.6.7) . Curiosly its works ONLY separating by space not by dot (for exampe: 1 5 6 7). This number should be fixed only inside of texbox. private string strcut( string str) { string [] a = str.Trim().Split( ' ' ); string str1 = string .Empty; for ( int i = 0; i { str1 = str1 + a[i]; if (a.Count() - 2 != i) { str1 += " " ; } } return str1; } private void btnTest_Click( object sender, EventArgs e) { string str = textBox1.Text; MessageBox.Show(strcut(str)); }

Can you tell me, what's not working? That's what I had optimized your 7 lines of code to 1 line, which gives the same output. private string strcut( string str) { var str1= "" ; //"1.5.6.7"; if (str.Length>=2) str1 = str.Substring(0, str.Length - 2); return str1; } output: 1.5.6

Ideally, Amit solution should work but if not then let me solve in other way for you. var temp = str.Trim().Split( '.' ); var str2 = string.Join( "." , temp.Take(temp.Count() - 1));

Thank you Amit. But its doesnt work. Later I do resolve it like this. Maybe can help anyone in the same situation. private string strcut( string str) { string [] a = str.Trim().Split( '.' ); //Adding a dot here string str1 = string .Empty; for ( int i = 0; i { str1 = str1 + a[i]; if (a.Count() - 2 != i) { str1 += "." ; } //Adding a dot also here } return str1; } private void btnTest_Click( object sender, EventArgs e) { string str = textBox1.Text; //MessageBox.Show(strcut(str)); textBox1.Text = strcut(str); }

var str = StringValue.Substring(0, StringValue.Length -2);
