c# - Getting Error Msg - Cannot implicitly convert type 'string' to 'bool'

I am checking for values in a textbox to trigger a conditional statement, but am getting error messages.

if (txtAge.Text = "49") || (txtAge.Text = "59")
{
    txtNote.Text = "A valid picture ID must be submitted";
}

The error message I am getting is Cannot implicitly convert type 'string' to 'bool'

How can I resolve this?

In the if statement replace = by ==.

You're using the assignment operator instead of the equals comparison.

The syntax for the if statement is also not correct. Check if-else (C# Reference).
