SqlDbType Chars's And VarChar's

I have an overloaded method in my data access layer that I use to load the parameters into a command object.  One of these overloaded methods is as follows:

public void LoadSqlParameter(string name, string value, ParameterDirection direction)
{
            param                           = new SqlParameter();
            param.ParameterName = name;
            param.Value                 = value;
            param.Direction            = direction;

            param.SqlDbType        = SqlDbType.VarChar;

            cmd.Parameters.Add(param);
}

Will using a SqlDbType of VarChar cause me any problems if the actual parameter in the stored procedure is a Char? 

Am I better off leaving out the line that specifies the type?

Thanks
