What's the # in front of a string in C#?
(9 answers)
Closed 7 years ago.
How come this string is valid to open with VLC via a Process:
string fileToPlay = #"C:\Videos\Movies\Movie title.avi";
But this one isn't:
string fileToPlay = #myMovie;
Where the value of the variable myMovie is
"C:\Videos\Movies\Movie title.avi"
Process.Start(vlcPath, fileToPlay );
The problem is that you can only use the # character when placed against string literals like this:
string path = #"c:\temp";
It can be used when placed against a string variable, as you have done, but it has a different meaning. In that case, it is used when you choose an identifier which matches a C# keyword, like this:
string #class = "hello";

How do i split a String into multiple values?

Not entirely sure the following code is going to help many people, but here goes
try
{
uvConnect = UniObjects.OpenSession(serverId, sUser, sPass, sAcct, "uvcs");
// Open Movie File
UniFile uvFile = uvConnect.CreateUniFile("MOVIES");
UniDynArray movieRec = uvFile.Read(txtMovieId.Text);
string sMovieData = movieRec.StringValue;
MessageBox.Show(sMovieData);
}
sMovieData contains a single string of the entire record retrieve from MOVIES file, each field is deliminated by a char(253) character in the database I am using.
Is there a function/method/etc to convert the string to an array using char(253) as a value deliminator
Something like this should work:
string[] fields = sMovieData.Split((char)253);
Try this... string[] arrayValues = "stringToConvertToArray".Split((char)253);

New Line in Constant error when trying to insert escape character in string
(3 answers)
Closed 4 years ago.
I am trying to do a Path.Combine. One string is the path and the other is just a slash.
string ok = browser.SelectedPath;
string okie = "\";
string pathy = Path.Combine(ok, okie);
Settings.Default["Path"] = pathy;
for
string okie = "\";
I get two errors NewLine in constant. Anyone know how to fix this?
Thank you!
Get rid of okie and pathy, and assign Settings.Default["Path"] the browser.SelectedPath, eg
Settings.Default["Path"] = browser.SelectedPath;

How do I replace a backslash-double quote with just a double quote?
(3 answers)
Closed 5 years ago.
I am working on a c# project and have some strings like this
first string
"[\"2018\\/02\\/12\",[\"Test1\",\"Test2\",\"Test3\",\"Test4\"]]"
But this string format is not not suitable for my application. I want to change first string to this :
second string
2018-02-12,"Test1","Test2","Test3","Test4"
I've done some of it, but I'm having trouble getting a backslash. Actually backslash did not changed.
my code :
string MyString = "[\"2018\\/02\\/12\",[\"Test1\",\"Test2\",\"Test3\",\"Test4\"]]";
MyString = MyString.Replace("[", "").Replace("]", "").Replace("\\", "");
How can I get the second string?
Use the following code:
MyString.Replace("[", string.Empty).Replace("]", string.Empty).Replace("\\", string.Empty).Replace(#"\", string.Empty).Replace("/", "-");
And view the result in Text Visualizer.

string id = oUser.id.ToString();
Image1.ImageUrl="http://graph.facebook.com/893914824028397/picture?type=large&redirect=true&width=500&height=500";
I want to replace 893914824028397 by string id
You can use String Interpolation feature from C#6, so your code will look like:
string id = oUser.id.ToString();
Image1.ImageUrl=$"http://graph.facebook.com/{id}/picture?type=large&redirect=true&width=500&height=500";

C# string replace does not actually replace the value in the string [duplicate]

I'm getting a string from a Json :
var value = JsonObject["price"]; //value = "1,560";
i'm trying to replace the ',' with an empty string :
value.Replace(",",string.Empty);
but i'm still getting the value with "," that's so strange and i'm stuck at it
thanks in advance
value = value.Replace( ", ", string.Empty);
strings in .net are immutable.
Per the documentation for String.Replace:
Returns a new string in which all occurrences of a specified string in the current instance are replaced with another specified string.
It gives you a new string; it doesn't modify the existing one. So you need to assign the result to a variable:
value = value.Replace(",", string.Empty);
