Split a string in array by a string delimiter in C#

private static string[] SplitString(string valueString, string delimiter)

{

        string[] RetVal;

        int Index = 0;

        string Value;

        List<string> SplittedList = new List<string>();

        while (true)

        {

            Index = valueString.IndexOf(delimiter);

            if (Index == -1)

            {

                if (!string.IsNullOrEmpty(valueString))

                {

                    SplittedList.Add(valueString);

                }

                break;

            }

            else

            {

                Value = valueString.Substring(0, Index);

                valueString = valueString.Substring(Index + delimiter.Length);

                SplittedList.Add(Value);

               

            }

        }

        RetVal = SplittedList.ToArray();

        return RetVal;

}

Parse an XML string/file for a single node in C#

string myXMl = "<Employees>" +
                 "<Employee ID='1' Name='Ravi'" +
                      "Address='Pandav Nagar'" +
                      "City='New Delhi' Zip='110092'>" +
                 "</Employee>" +
               "</Employees>";

XmlDocument xDoc = new XmlDocument();
xDoc.LoadXml(myXMl);

XmlNode xmlNode = xDoc.SelectSingleNode("/Employees/Employee[@ID='1']");

string Name = xmlNode.Attributes["Name"].Value;//Outputs: Ravi
string Address = xmlNode.Attributes["Address"].Value;//Outputs: Pandav Nagar
string City = xmlNode.Attributes["City"].Value;//Outputs: New Delhi
string Zip = xmlNode.Attributes["Zip"].Value; //Outputs: 110092

Parse an XML string/file in C#

The following code shows a simple method of parsing through an XML string/file. We can get the parent name, child name, attributes etc. from the XML. The namespace System.Xml would be the only additional namespace that we would be using.

string myXMl = "<Employees>" +
                 "<Employee ID='1' Name='Ravi'" +
                      "Address='Pandav Nagar'" +
                      "City='New Delhi' Zip='110092'>" +
                 "</Employee>" +
               "</Employees>";

XmlDocument xDoc = new XmlDocument();
xDoc.LoadXml(myXMl);

XmlNodeList xNodeList = xDoc.SelectNodes("Employees/child::node()");
foreach (XmlNode xNode in xNodeList)
{
  if (xNode.Name == "Employee")
  {
    string ID = xNode.Attributes["ID"].Value; //Outputs: 1
    string Name = xNode.Attributes["Name"].Value; //Outputs: Ravi
    string Address = xNode.Attributes["Address"].Value; //Outputs: Pandav Nagar
    string City = xNode.Attributes["City"].Value; //Outputs: New Delhi
    string Zip = xNode.Attributes["Zip"].Value; //Outputs: 110092
  }
}

Lets look at another XML:

string myXMl = "<root>" +
                 "<parent1>Some Data</parent1>" +
                 "<parent2>" +
                   "<Child1 id='1' name='d1'>data1</Child1>" +
                   "<Child2 id='2' name='d2'>data2</Child2>" +
                 "</parent2>" +
               "</root>";

XmlDocument xDoc = new XmlDocument();
xDoc.LoadXml(myXMl);
XmlNodeList xNodeList = xDoc.SelectNodes("root/child::node()");

//Traverse the entire XML nodes.
foreach (XmlNode xNode in xNodeList)
{
    //Looks for any particular nodes
    if (xNode.Name == "parent1")
    {
        //some traversing....
    }

    if (xNode.Name == "parent2")
    {
        //If the parent node has child nodes then
        //traverse the child nodes
        foreach (XmlNode xNode1 in xNode.ChildNodes)
        {
           string childNodeName = xNode1.Name;      //Ouputs: Child1
           string childNodeData = xNode1.InnerText; //Outputs: data1

           //Loop through each attribute of the child nodes
           foreach (XmlAttribute xAtt in xNode1.Attributes)
           {
               string attrName = xAtt.Name;   //Outputs: id
               string attrValue = xAtt.Value; //Outputs: 1
           }
        }
    }
}

Custom Date Formatting in C#

Every object has a method called ToString that returns a string representation of the object. The ToString method can accept a string parameter, which tells the object how to format itself – in the String.Format call, the formatting string is passed after the position, for example, “{0:##}”.

The text inside the curly braces is {index[,alignment][:formatString]}. If alignment is positive, the text is right-aligned in a field the given number of spaces; if it’s negative, it’s left-aligned.

Specifier	Type	Example	Example Output
dd	Day	{0:dd}	10
ddd	Day name	{0:ddd}	Tue
dddd	Full day name	{0:dddd}	Tuesday
f, ff, …	Second fractions	{0:fff}	932
gg, …	Era	{0:gg}	A.D.
hh	2 digit hour	{0:hh}	10
HH	2 digit hour, 24hr format	{0:HH}	22
mm	Minute 00-59	{0:mm}	38
MM	Month 01-12	{0:MM}	12
MMM	Month abbreviation	{0:MMM}	Dec
MMMM	Full month name	{0:MMMM}	December
ss	Seconds 00-59	{0:ss}	46
tt	AM or PM	{0:tt}	PM
yy	Year, 2 digits	{0:yy}	2
yyyy	Year	{0:yyyy}	2002
zz	Timezone offset, 2 digits	{0:zz}	-5
zzz	Full timezone offset	{0:zzz}	-05:00
:	Separator	{0:hh:mm:ss}	10:43:20
/	Separator	{0:dd/MM/yyyy}	10/12/2002

 

Ex:

string.Format("{0:yyyy-MM-dd}", DateTime.Today.Date)

Output:

2011-09-28
