Hi

In your C# Web Application, In the aspx page Use RegularExpressionValidator

<asp:TextBox ID="TextBoxEmail" runat="server"><asp:TextBox>

<asp:RegularExpressionValidator ID="RegularExpressionValidatorTextBoxEmail" ControlToValidate="TextBoxEmail"

runat="server" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"

ErrorMessage="Enter valid Email"></asp:RegularExpressionValidator>

Hi Sravanti,

You can try the below code...

string Email_Expression;

private void button1_Click(object sender, EventArgs e)

{

Email_Expression ="^[a-zA-Z][\\w\\.-]{2,28}[a-zA-Z0-9]@[a-zA-Z0-9][\\w\\.-]*[a-zA-Z0-9]\\.[a-zA-Z][a-zA-Z\\.]*[a-zA-Z]$" ;

if (textBox1.Text != null)

{

if (Regex.IsMatch(textBox1.Text, Email_Expression))

MessageBox.Show("You have entered Correct Email ID");

else

MessageBox.Show("Please Enter Email Correctly");

}

Thanks & Regards

Hey You can use this code

/^[a-zA-Z0-9._-]+@[a-zA-Z0-9-.]+\.[a-zA-Z]{2,4}$/;

In C# Web Application Use RegularExpressionValidator

Select Property and Change

ControlToValidate="textboxID"
ValidationExpression="^[a-zA-Z][\w\.-]{2,28}[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"
ErrorMessage="Please Enter Email ID"
