Get SPListItem value using field InternalName
You can get a field value of SPListItem object using its display name like SPListItem[“yourFieldName”] but this does not work always. Because SPListItem indexer require Field Internal name that sharepoint use. Most of the time Display name and internal name is same. but if your display name has some special character in it etc then sharepoint will keep Internal name different. In any case you should always use Field internal name to get SPListItem column value. This is a best practice
//Assuming here that you already have your SPWeb object with the variable name web.
SPList yourList = web.Lists["Your list name"];
//Assuming here that you already have your SPLISTItem
//object with the variable name oSPListItem.
string sColumnValue = oSPListItem[yourList.Fields["yourSiteColumn display name"].InternalName].ToString();
