When you debug the program, on what line the exception occurs?

Solution 1

Most likely cLeaveReq.Get method accepts a boolean parameter and you are passing it an integer Convert.ToInt32(LeaveReqid). You need to change either the method or the call to the method.

my Get method accept only integer
public HR.Dal.Model.Leave_Request Get(int recordId);

Wrong, if it would accept integer values then there would have been no problem at all. The problem is with this parameter, that you are casting to integer. It needs to be a boolean.

Then you have to post some more code, in order to get help.

this one is my controllers' class method

public Model.Leave_Request Get(int recordId)
{
Model.Leave_Request iObject = null;
DBManager dbManager = null;
IDataReader iReader = null;
string sql = string.Empty;

try
{
sql = "SELECT LEAVE_REQUEST_ID,EMP_NO,FROM_DATE,TO_DATE,REQUEST_TYPE_ID,APPROVAL_DATE,IS_APPROVED FROM dbo.LEAVE_REQUEST WITH(NOLOCK) WHERE IS_DELETED=0 AND LEAVE_REQUEST_ID= " + recordId;

switch (Constants.DBEngine)
{
case (int)DataProvider.SqlServer:
dbManager = new DBManager();
dbManager.ProviderType = DataProvider.SqlServer;
dbManager.ConnectionString = Constants.ConnectionString;
break;
}
dbManager.Open();
dbManager.Command.CommandTimeout = Constants.CommandTimeOut;
dbManager.Command.CommandText = sql;
dbManager.Command.Connection = dbManager.Connection;
iReader = dbManager.Command.ExecuteReader();
iObject = iReader.SingleOrDefault<model.leave_request>();
}
catch (Exception Exp)
{
throw Exp;
}
finally
{
if (iReader != null)
iReader.Close();
if (dbManager != null)
dbManager.Close();
}
return iObject;
}

In the following line pls try
sql = "SELECT LEAVE_REQUEST_ID,EMP_NO,FROM_DATE,TO_DATE,REQUEST_TYPE_ID,APPROVAL_DATE,IS_APPROVED FROM dbo.LEAVE_REQUEST WITH(NOLOCK) WHERE IS_DELETED=Cast(0 as BIT) AND LEAVE_REQUEST_ID= " + recordId;
