How to read / write file Summery Info ???

Hi sateesh....

Available fields are:
"CompanyName"
"FileDescription"
"FileVersion"
"InternalName"
"LegalCopyright"
"OriginalFileName"
"ProductName"
"ProductVersion"

only. so how about Title,  author, comment etc??? 

Use FileInfo and FileVersionInfo object to get the properties as shown below:
System.Diagnostics.FileVersionInfo fileVersion = System.Diagnostics.FileVersionInfo.GetVersionInfo(filePath);
