unassigned-variable

I'm doing the following block of code and the compiler is complaining about unassigned local variables and could use some help identifying what's up. while (rsData.Read()) { if (rsData["TYPE"] != DBNull.Value) strType = rsData["TYPE"].ToString().Trim(); if (strType == "01") { if (rsData["Text"] != DBNull.Value) strwho = rsData["Text"].ToString(); if ((strwho.Length < 10 || (strwho.IndexOf("NULL") > 1))) strwho = ""; } else if (strType == "07") { if (rsData["Text"] != DBNull.Value) strmetades = rsData["Text"].ToString(); if ((strmetades.Length < 10 || (strmetades.IndexOf("NULL") > 1)))

I am reading connection strings from my App.config file and for that i have following code. try { string[] dbnames; int counter = 0; foreach (ConnectionStringSettings connSettings in ConfigurationManager.ConnectionStrings) { dbnames[counter] = connSettings.Name; counter++; } return dbnames; } catch { throw; } this code giving me error use of unassigned local variable for dbnames. i will have multiple connection strings in my App.config. They can be none,1,2 and so on. Depending on the needs. so i cant statically assign the dbname size. Because there can be a scenario if they exceed the value

I am getting an error use unassigned local variable 'multidimension' from below code. I am trying to put the data returned back from the text file in a multidimensional array by splitting them and put each row in in the array private void button1_Click_1(object sender, EventArgs e) { string[,] Lines; //string[][] StringArray = null; //to get the browsed file and get sure it is not curropted try { DialogResult result = openFileDialog1.ShowDialog(); if (result == DialogResult.OK) { using (StreamReader sr = new StreamReader(openFileDialog1.FileName)) { string[] data= null; string ReadFromReadLine

Just curious. If you go: string myString; Its value is null. But if you go: int myInt; What is the value of this variable in C#? Thanks David Firstly, note that this is only applicable for fields, not local variables - those can't be read until they've been assigned, at least within C#. In fact the CLR initializes stack frames to 0 if you have an appropriate flag set - which I believe it is by default. It's rarely observable though - you have to go through some grotty hacks. The default value of int is 0 - and for any type, it's essentially the value represented by a bit pattern full of zeroes

I'm new to programming and having a problem with the following code: private string alphaCoords(Int32 x) { char alphaChar; switch (x) { case 0: alphaChar = 'A'; break; case 1: alphaChar = 'B'; break; case 2: alphaChar = 'C'; break; case 3: alphaChar = 'D'; break; case 4: alphaChar = 'E'; break; case 5: alphaChar = 'F'; break; case 6: alphaChar = 'G'; break; case 7: alphaChar = 'H'; break; case 8: alphaChar = 'I'; break; case 9: alphaChar = 'J'; break; } return alphaChar.ToString(); } The compiler says: Use of unassigned local variable 'alphaChar' But I'm assigning it in my switch block.
