Asp.net interview questions

Part 1: questions about C # And Asp.net
1. Briefly describe the differences between private and protected

2. Differences between the following functions:
Private void test (string Str ){...}
Private void test (ref string Str ){...}
Private void test (out string Str ){...}

3. WriteCode: Get the server time and display it (in the pop-up message box). It must be fully implemented on the server side (Tip: Use the response. Write () method in C)

4. give reasons for the following errors or errors (written in this row)
Class Test
{
Int X;
Static int y;
Void F (){
X = 1; // OK
Y = 1; // OK
}
Static void g (){
X = 1; // Error
Y = 1; // OK
}
Static void main (){
Test T = new test ();
T. X = 1; // OK
T. y = 1; // Error
Test. x = 1; // Error
Test. y = 1; // OK
}
}

4. Briefly Talk about your understanding of polymorphism and a simple example of how to implement polymorphism.

Part 2: javascript-related

1. explain the meaning of the following statements:
A. V1 = opener. V1;

B. If (100 =" 100" ){...}

C. If (100 =" 100" ){...}

D. Function printblank (){
VaR coll = Document. All;
If (Coll! = NULL ){
For (I = 0; I <Coll. length; I ++ ){
If (Coll. Item (I). tagname = "input "){
Coll. Item (I). style. Visibility = "hidden ";
}
}
}
}

2. output results
A. var x = 0/0;
If (X! = X ){
Document. Write ("X! = X ");
} Else {
Document. Write ("x = x ");
}

B. var I = 1;
Switch (I)
{
Case 1:
Case 2: Alert ("good"); break;
Case 3: Alert ("end"); break;
}

3. If a page frequently interacts with the database, but the page cannot be refreshed too badly, what are your best methods?

Part 3: ms SQL Server

1. The following describes the index. Which of the following statements are true? ()
A. indexing can speed up queries
B. indexes may reduce the update speed of values.
C. create as many indexes as possible for the table

2. Use tsql to implement:
A. If a table (Table1) exists, delete it. Otherwise, create a table (assuming that the table has only one varcahr (50) field)
B. use the SELECT statement to return a table (sex char (2) based on the sex value in table 1 (sex bit). The rule is as follows: 'male' is returned when sex is 0 ', if the value is 1, 'femal' is returned '.

3. In the existing table Table1 Table2, the fields are the same ([name] varchar (10). To obtain the names not in Table2 in Table1, write an SQL statement.

4. To write a stored procedure, you must input a table name and return the number of records of the table (assuming that the input table exists in the Database)

1. Test A design model related: the factory mode or command works, which are commonly used.

2. Test A face object, including ref parameter transfer + collection class + serialization

3. Take a modeling test: design of the organization and permissions

4. Actual Operation: Use sqlserver + Asp.net to add, delete, and modify data in a table, and search by PAGE and sort.
