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 < a.Count() - 1; 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 < a.Count() - 1; 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);
