Regular Expression for Letters and Spaces

Question

I have a string variable in C# and I want to check this string contains letters or not.

I used following regular expression for evaluate this condition, but I returned false in the if statement I used.

I dont know why?

My C# Code:

 string cellValue ="Row Merging Done here";
 if (Regex.IsMatch(cellValue, @"^[a-zA-Z]+$"))
 {
     messageBox.show("Message found");
 }

How to evalute this regular expression?

Answer 1

您是否不需要识别空格： @"^[a-zA-Z ]+$"

Do you need to check whether the string contains at least one word? If so, you don't need symbols for beginning and end:

if (Regex.IsMatch(cellValue, @"[a-zA-Z]+"))
