C# variable in an xpath selector

Question

Can I pass a C# string variable into an xpath selector? This is for a selenium unit test. I want to do something like this:

string myText = "foo";    
Assert.IsTrue(Browser.IsElementPresent("//option[contains(text(), $myText)]"));

Answer 1

使用string.Format应该可以工作：

Assert.IsTrue(Browser.IsElementPresent(string.Format("//option[contains(text(), {0}]",myText)));

Answer 2

yes you can use String.Format

string myText = "foo";    
Assert.IsTrue(Browser.IsElementPresent(String.Format("//option[contains(text(), {0})]", myText)));

Answer 3

I see this has already been answered but you could also just do:

Assert.IsTrue(Browser.IsElementPresent(String.Format("//option[contains(text(), " + myText + ")]")));

This works because C# will just append each string to the end of the other.

Answer 4

Thank you for your answers! I was doing a Find in a table, and the above solutions did not work for me, possibly because my string contained hyphens, a decimal point, and numerals like so: "TV-8888-ZIP-54-EN-CTR.05021031"

I assigned the string to the C# variable ID. The answers above failed, I suspect, due to the decimal point and numerals. Using Nashibukasan's answer, I had to explicitly add single quotes. The working Find statement--that gets the value in the third column of the table from the same row that contains the ID string in the first column--ended up looking like this:

value = driver.FindElement(By.XPath(string.Format("//td[contains(text()," + "'" + ID + "'" + ")]/following-sibling::td[2]"))).Text;
