MinimumSqlDate

The default SQL date used by InitializeDataRowWithBlanks. Considered a blank date instead of null.

CloseConnection

Closes a connection

public static void CloseConnection(SqlCommand Command)

CopyDataRow

Copies the content of a data row to another. Runs through the target's fields and looks for fields of the same name in the source row. Structure must mathc or fields are skipped.

public static bool CopyDataRow(DataRow source,     DataRow target)

CopyObjectData

Copies the content of one object to another. The target object 'pulls' properties of the first.

public static void CopyObjectData(object source,     object target)

public static void CopyObjectData(object source,     object target,     BindingFlags memberAccess)

public static void CopyObjectData(object source,     object target,     string excludedProperties)

public static void CopyObjectData(object source,     object target,     string excludedProperties,     BindingFlags memberAccess)

CopyObjectFromDataRow

public static void CopyObjectFromDataRow(DataRow row,     object targetObject)

CopyObjectToDataRow

Copies the content of an object to a DataRow with matching field names. Both properties and fields are copied. If a field copy fails due to a type mismatch copying continues but the method returns false

public static bool CopyObjectToDataRow(DataRow row,     object target)

DataReaderToIEnumerable<T>

Creates an IEnumerable of T from an open DataReader instance.

public static IEnumerable DataReaderToIEnumerable(IDataReader reader,     string fieldsToSkip,     Dictionary<String,PropertyInfo> piList)

DataReaderToObject

Populates the properties of an object from a single DataReader row using Reflection by matching the DataReader fields to a public property on the object passed in. Unmatched properties are left unchanged.

public static void DataReaderToObject(IDataReader reader,     object instance,     string fieldsToSkip,     Dictionary<String,PropertyInfo> piList)

DataReaderToObjectList<T>

Creates a list of a given type from all the rows in a DataReader.

public static List DataReaderToObjectList(IDataReader reader,     string fieldsToSkip,     Dictionary<String,PropertyInfo> piList)

DbTypeToDotNetType

Maps a DbType to a .NET native type

public static Type DbTypeToDotNetType(DbType sqlType)

DotNetTypeToDbType

Converts a .NET type into a DbType value

public static DbType DotNetTypeToDbType(Type type)

DotNetTypeToSqlType

Converts a .NET type into a SqlDbType.

public static SqlDbType DotNetTypeToSqlType(Type type)

GenerateUniqueId

public static string GenerateUniqueId(int stringSize)

GenerateUniqueNumericId

public static long GenerateUniqueNumericId()

GetDataTable

Returns a DataTable from a Sql Command string passed in.

public static DataTable GetDataTable(string Tablename,     string ConnectionString,     string Sql,     SqlParameter[] Parameters)

GetRandomNumber

Returns a random integer in a range of numbers a single seed value.

public static int GetRandomNumber(int min,     int max)

GetSqlCommand

Creates a Command object and opens a connection

public static SqlCommand GetSqlCommand(string ConnectionString,     string Sql,     SqlParameter[] Parameters)

GetSqlDataReader

Returns a SqlDataReader object from a SQL string.

public static SqlDataReader GetSqlDataReader(string ConnectionString,     string Sql,     SqlParameter[] Parameters)

InitializeDataRowWithBlanks

Initializes a Datarow containing NULL values with 'empty' values instead. Empty values are: String - "" all number types - 0 or 0.00 DateTime - Value of MinimumSqlData (1/1/1900 by default); Boolean - false Binary values and timestamps are left alone

public static void InitializeDataRowWithBlanks(DataRow row)

SqlTypeToDotNetType

Maps a SqlDbType to a .NET type

public static Type SqlTypeToDotNetType(SqlDbType sqlType)
