           DataRow oOrderRow;
           OleDbConnection conn = new OleDbConnection(strConString);
           DataSet oDs = new DataSet();
           OleDbDataAdapter oDbAdapter = new OleDbDataAdapter(new OleDbCommand(strSql, conn));
           OleDbCommandBuilder oDbCmdBuilder = new OleDbCommandBuilder(oDbAdapter);
           oDbAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
           oDbAdapter.Fill(oDs, "AT_ASSET_MASTER");
           // Insert the Data
           oOrderRow = oDs.Tables["AT_ASSET_MASTER"].NewRow();
           oOrderRow["ASSET_NAME"] = AssetName;
           oOrderRow["ASSET_TYPE_ID"] = assetTypeID;

Solution 1

Check the type on one of the following lines (19th param):

C#

oOrderRow["USEFUL_LIFE_YEAR"] = DepreciationLife;
oOrderRow["DEPRECIABLE_COST"] = Convert.ToDouble(DepreciableCost);

Run in a debugger and check the object types.

Try and empty dataset as follows (add a where clause)

string strSql = "select ASSET_NAME,ASSET_TYPE_ID,QTY,UNIT_ID,UNIT_COST,ACQUISITION_DATE,RATE_OF_DEPRE,ASSET_COST,ACQUISITION_COST,ACQUISITION_EXPENSE,INSTALLATION_COST,BOOK_VALUE,DEPRECIABLE_COST,TOTAL_DEPRE_CHARGED,SALVAGE_VALUE,IDENTIFICATION_MARK,USEFUL_LIFE_YEAR,DEPT_ID,VENDOR_ID,DESCRIPTION,PARTICULARS,FIRST_YEAR_DEPRE_RATE,INITIAL_DEPRE_AMT,COST_VOUCHER_NO,TOTALASSETCOST,ASSETNO,CMP_BRANCH_ID,MEETINGNO from AT_ASSET_MASTER where 1=-1";
