In this article we will discuss how can we convert first letter to upper case using C#.Net. Also you can check my last article on how to check if string contains a particular string in C#.Net here. Also you can see a very good article on Remove HTML tags from string in C#.Net.
Below is the full code:
Html code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Convert first letter to uppercase in C#.Net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtEnterText" runat="server"></asp:TextBox><br />
<asp:Button ID="btnTest" runat="server"
Text="Convert First Letter To UpperCase" onclick="btnTest_Click" /><br />
<asp:Label ID="lblResult" runat="server" Text=""></asp:Label>
</div>
</form>
</body>
</html>
.cs code:
protected void btnTest_Click(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(txtEnterText.Text))
{
char[] allLetters = txtEnterText.Text.Trim().ToCharArray();
allLetters[0] = char.ToUpper(allLetters[0]);
string outPut = new string(allLetters);
lblResult.Text = outPut;
}
}
The output will appear like below:
