Hi padmanabhan thanks for ur reply..., we can use this following method it will work fine? if(lgtext.indexof(shtext)!=-1) { 'found' } else { 'not found' } is't ok?

Why would you even split this? String class has Contains method. Use it.

contains method won't give exact search.. eg., string search = text1,text2,text3,text4; if we want to search for "text" in this, by using contains will give found message for all the condition. But my output must be exactly "text" which is not present in the string. so, for most of the requirements contains wont provide exact result.

Agreed. Provided the string structure remains same, check for the trailing comma as well after the text to match. This would work.

This will not work for below string string lgtext = "text5, text2, text6, text4, text7text8 "; And you have find exact "text8". if you use Contains then it returns true but text8 is not in the collection. So better to use below code. protected void Button1_Click(object sender, EventArgs e) { string lgtext = "text5, text2, text6, text4"; string shtext = "text2"; string[] split = lgtext.Split(','); for(int i=0;i&lt; =split.Length-1;i++) { if(split[i].Contains(shtext)) Response.Write("Found"); } }
