Kauj Ruam 4: Ua ntej Sau Txoj Cai

Xyuas kom koj daim ntawv zoo li qhov no thiab DataGridView lub npe "GRID". Koj tuaj yeem teeb nws hauv qhov tsim nyog qhov rai

Kauj Ruam 5: Sau Txoj Cai

Nyem ob zaug ntawm txhua ntu ntawm koj cov ntawv qhia zaub mov, txhawm rau tsim cov xwm txheej, txhua lub sijhawm lub qhov rai nrog tus lej yuav pom, yog li rov qab mus rau nws nrog txhua qhov (Txuag, Qhib, Kaw) Qhov peb xav tau hauv tus lej: ntiag tug tsis muaj dab tsi SaveToolStripMenuItem_Click (tus neeg xa khoom, EventArgs e) {} ntiag tug tsis muaj dab tsi OpenToolStripMenuItem_Click (tus xa khoom, EventArgs e) {} ntiag tug tsis muaj dab tsi CloseToolStripMenuItem_Click (tus xa khoom, EventArgs e) {}

Kauj Ruam 6: Code Code Code…

Nov yog tus lej tag nrho ntawm peb daim ntawv thov nrog cov lus pom tom qab "//" cov xwm txheej: siv System; siv System. Collections. Generic; siv System. ComponentModel; siv System. Data; siv System. Drawing; siv System. Linq; siv System. Ntawv; siv System. IO; // ntxiv siv System. Windows. Forms; siv System. Runtime. Serialization. Formatters. Binary; // ntxiv siv System.

EndEdit (); SaveFileDialog saveFileDialog1 = tshiab SaveFileDialog (); // Tsim cov ntawv khaws cia sib tham saveFileDialog1. RestoreDirectory = muaj tseeb; // nyeem thiab lim cov ntaub ntawv raw yog (saveFileDialog1. ShowDialog () == DialogResult. OK) {BinaryFormatter formatter = tshiab BinaryFormatter (); FileStream tso tawm = FileStream tshiab (saveFileDialog1. FileName, FileMode. OpenOrCreate, FileAccess. Write); ' int n = GRID.

Value. ToString (); Tus neeg .surname = GRID [1, i]. Value. ToString (); Tus neeg .city = GRID [2, i]. Value. ToString (); Tus neeg .number = GRID [3, i]. Value. ToString (); } formatter. Serialize (tso tawm, Tus neeg); tso tawm. Close (); }} ntiag tug tsis muaj dab tsi OpenToolStripMenuItem_Click (tus xa khoom, EventArgs e) // Nyeem Ntawv thiab ntxiv cov ntaub ntawv rau GRID {openFileDialog1 = tshiab OpenFileDialog (); yog (openFileDialog1. ShowDialog () == DialogResult. OK) {BinaryFormatter nyeem ntawv = tshiab BinaryFormatter (); FileStream cov tswv yim = FileStream tshiab (openFileDialog1. FileName, FileMode. Open, FileAccess. Read); cov ntaub ntawv Tus neeg = (cov ntaub ntawv ) nyeem ntawv. Deserialize (tswv yim); GRID. Rows. Clear (); rau (int i = 0; i <Person. Length; i ++) {GRID. Rows. Add (); GRID [0, i].

Value = Tus neeg .number; }}} ntiag tug tsis muaj dab tsi CloseToolStripMenuItem_Click (tus xa khoom, EventArgs e) {Kaw (); // kaw ib qho app}}}

Kauj ruam 7: Nws Ua tiav. Kuaj Nws

Nyem rau ntawm cov ntawv qhia zaub mov Debug hauv Visual Studio dua li pib Debugging nws yuav tsum ua haujlwm. Sim sim lub app. Kuv paub tseeb tias koj yuav pom qee qhov kab, peb daim ntawv thov yooj yim heev yam tsis muaj kev ruaj ntseg thaum txuag, qhib cov ntaub ntawv, nws tsuas yog ua piv txwv yuav ua li cas thiaj li ua tau daim ntawv thov loj dua.
