Setting Built In and Custom Document Properties using C#

Create a new windows application project and add a button to it.

On click of that button, we will open a document and add values for a built in and custom document properties.

Than add reference to (Word 10.0 or 11.0 object library) and Microsoft.Office.Core.dll within COM tab of Add reference dialog box.

After adding reference, add this directive

using Microsoft.Office.Interop.Word

using System.Reflection;

Put the following code in the button click event handler

// For optional parameters create a missing object

object missing = System.Reflection.Missing.Value;

// Create an object for filename which is the file to be opened

object fileName = @”C:\MySecond.doc”;

// Create an object of application class

ApplicationClass WordApp = new ApplicationClass();

// open the document specified in the fileName variable

Document adoc = WordApp.Documents.Open(ref fileName, ref missing, ref missing, ref missing, ref missing,

ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,

ref missing, ref missing, ref missing);

 

// setting the document built in properties

object oDocBuiltInProps = adoc.BuiltInDocumentProperties;

Type typeDocBuiltInProps = oDocBuiltInProps.GetType();

// setting the Title property with value “My Proposal”

string strIndex = “Title”;

string strValue = “My Proposal”;

typeDocBuiltInProps.InvokeMember(“Item”,

BindingFlags.Default |

BindingFlags.SetProperty,

null, oDocBuiltInProps,

new object[] { strIndex, strValue });

 

 

// setting the custome document properties

object oDocCustomProps = adoc.CustomDocumentProperties;

Type typeDocCustomProps = oDocCustomProps.GetType();

// setting the ProposalSentDate custom date property with current date time

string strIndex1 = “ProposalSentDate”;

string strValue1 = DateTime.Now.ToShortDateString();

object[] oArg = { strIndex1, false, Microsoft.Office.Core.MsoDocProperties.msoPropertyTypeDate, strValue1 };

typeDocCustomProps.InvokeMember(“Add”,

BindingFlags.Default |

BindingFlags.InvokeMethod, null,

oDocCustomProps,oArg);

 

WordApp.Visible = true;

 

Byee…
