Jan 29, 2017
Introduction:

jQuery Remove first or last characters from string, Delete selected rows from datatable in c#, vb.net and many articles relating to Asp.net, Gridview, Ajax, JQuery. Now I will explain how to remove last character from string in c#, vb.net with example.

We have different ways to remove the last character from string in c#, vb.net based on our requirements.

Following are the few methods which we can use to remove last character from string.
Method 1
Following is the one way of removing last character from string using Remove property
C# Code

protected void Page_Load(object sender, EventArgs e)
{
string istr = "1,2,3,4,5,6,7,8,9,10,";
string ostr = istr.Remove(istr.Length - 1, 1);
Response.Write(ostr);
}

VB.NET


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
Dim istr As String = "1,2,3,4,5,6,7,8,9,10,"
Dim ostr As String = istr.Remove(istr.Length - 1, 1)
Response.Write(ostr)
End Sub

Method 2

Following is the another way of removing last character from string using Trim property

C# Code


protected void Page_Load(object sender, EventArgs e)
{
string istr = "1,2,3,4,5,6,7,8,9,10,";
string ostr = istr.Trim(",".ToCharArray());
Response.Write(ostr);
}

VB.NET


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
Dim istr As String = "1,2,3,4,5,6,7,8,9,10,"
Dim ostr As String = istr.Trim(",".ToCharArray())
Response.Write(ostr)
End Sub

Method 3

Following is the another way of removing the last character from string using IndexOf property but that character should exists only one time otherwise this property will return the values before the first character.

C# Code


protected void Page_Load(object sender, EventArgs e)
{
string istr = "aspdotnet-suresh.com,";
string ostr = istr.Remove(istr.IndexOf(","));
Response.Write(ostr);
}

VB.NET


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
Dim istr As String = "aspdotnet-suresh.com,"
Dim ostr As String = istr.Remove(istr.IndexOf(","))
Response.Write(ostr)
End Sub
