Hai,

i need a solution for this.

String example="hi i am apple, coming from Bangalore,i am very tasty,";

i am going remove last "," from the example string:

example.RemoveAt(example.LastIndexOf(","));

I have been used String manipulation.RomoveAt method needs index position of the item where we need to delete an item.

Now u can get a string as:"hi i am apple, coming from Bangalore,i am very tasty"

I hope this will be useful for u...

Regards,

0	Try this DataTable dt = new DataTable(); dt.Columns.Add("Item"); dt.Rows.Add("abc@gmail.com"); dt.Rows.Add("xya@yahoo.com"); dt.Rows.Add("dfd@gmail.com"); //Solution 1: String.Join() var result1 = string.Join(",",dt.AsEnumerable().Select(row => row["Item"].ToString()).ToArray()); //Solution 2: Aggregate Extension Method var result2 = dt.AsEnumerable().Select(row => row["Item"].ToString()).Aggregate((a, b) => a + "," + b); Best Regards, Niladri Biswas Priti2010, if this helps please login to Mark As Answer. \| Alert Moderator

Try this

DataTable dt = new DataTable();

dt.Columns.Add("Item");

dt.Rows.Add("abc@gmail.com");

dt.Rows.Add("xya@yahoo.com");

dt.Rows.Add("dfd@gmail.com");



//Solution 1: String.Join()

 var result1 = string.Join(",",dt.AsEnumerable().Select(row => row["Item"].ToString()).ToArray());



//Solution 2: Aggregate Extension Method

 var result2 = dt.AsEnumerable().Select(row => row["Item"].ToString()).Aggregate((a, b) => a + "," + b);

0	Also you can use substr() and slice() in jquery to remove last comma om the string. var myString = "JavaScript"; var newString = myString.substr(0, myString.length - 4); // Result is now "JavaSc" var myString = "JavaScript"; var newString = myString.substr(2); // Result is now "vaScript" var strVal = $.trim($('.txtValue').val()); var lastChar = strVal.slice(-1); if (lastChar == ',' \|\| lastChar == '.') { strVal = strVal.slice(0, -1); } $("#result").text(strVal); Refer to http://dotnettec.com/remove-last-character-from-string-jquery/ Priti2010, if this helps please login to Mark As Answer. \| Alert Moderator

var myString = "JavaScript";
var newString = myString.substr(0, myString.length - 4);

// Result is now "JavaSc"

var myString = "JavaScript";
var newString = myString.substr(2);

// Result is now "vaScript"

var strVal = $.trim($('.txtValue').val());
var lastChar = strVal.slice(-1);
if (lastChar == ',' || lastChar == '.') {
strVal = strVal.slice(0, -1);
}
$("#result").text(strVal);
